At launch i tried a bit of every class and even though I played all the BWEs i didn't know the combat system very well. Now months after release I have tried all classes to at least 30+ and have a much better grasp of combat and combos and playing support. 

Now is there any class you played at launch that didn't click but now you love it?

For me it's easily mesmer. I have found so far this is probably the most versatile, customizable, and enjoyable class of them all. The things I can do on my memser most of my alts would have no chance at all(at my skill level that is heh)...I have changed my overall playstyle every 10 or so levels since I started playing it and closing in on 60 I have about 8 differn't builds I want to try once I open the last line of traits.

Also going the other way I really enjoyed warrior at launch but honestly find them the most boring class of them al nowl:P

First necro I made got to lvl 15 and I deleted. After the Mad King event, I re-created a necro and lvled to 80. Still not my favorite, but I find it much better now.

My necro is getting more dull as I lvl. He got a big boost at lvl 30 and he has been spinning his wheels since (75 now). My warrior is 30and a wrecking ball with fun weapons and seemingly interesting build choices. My 80 ranger is fun and has a nice variety of build choices. I def think the necro and engineer need a big fun injection of all the classes Ive tried (havent tried guardian or mesmer).

two best classes in the game IMHO:P 

2 classes for me.

The Theif, I never ever liked playing a rogue type character in any MMO, but in Gw2 I fell in love with way stealth works.

I also dig the Eng, at first I felt like it was ruff around the edges but now I get it, they are the kings of bunker-ing, as soon as I learned that they are not run and gun and played them the right way (one man fort) they really came to life.

Necromancer. 

I really like the class now.  I hated it with a passion before.  All the minions running around with a blood thirst I can't even describe, attacking everything in a three mile radius.  Dying pointlessly as though they were suicidal.  Insane creatures.  No control. 

Well they fixed that.  Minions now stay right with ya.  They've taken their medication and now behave.  Suddenly the class was made fun.  Good job Anet. 

Mesmer for me.

At release I tried and just couldnt get it to click, had much more fun on an engineer and thief so put my effort into them. With all the changes with laurels and dailys and such I figured it was a good time for a new character and went back to give Mesmer another go.

I think its partly that I chose the right race that appeals to me and also took my time exploring the options of the class more. Finding it a lot more exciting and deceitful now.

When I first started the game I hated mesmer and levelled my elementalist to 80.  Shortly after 80 I began to hate everything about elementalist and left the game for a few weeks.  After returning I though I would reroll a mesmer and see how it is, now I love the class and it has become my main.  I tried to get back on my elementalist after a few months away and after a half hour hopped back to the mesmer.  

same issue i think my elem is sitting near 70 right now.. but just got tired of playing the attunment dance.. but someone who has mastered swapping between all 4 elements is a sight to behold espeically in PVP

thief is another one i may try to get back into.. but right now loving the mesmer and guardian

Same for me. Mesmer. I hated it in Beta, but like it a lot more now that I'm a GW2 vet. :) Similar experience with Necromancer as well. Hated in in Beta, loving it so far (level 51) live.

There may have been some improvements to the professions since beta that made them more fun,. However, I think most of it is that I've learned a lot how to play the game since launch and those lessons or  just the general level of comfort with the game have made the difference.

I have six level 80s now and I'm working on getting the last two professions, (Necro and Engi) to 80 in the next month or two. The problem I'm having now is deciding which profession to settle into as my main moving forward.

I'm usually lucky to find two or three professions in an MMO that I really enjoy playing. With GW2, I enjoy pretty much all of them, with at least half being great matches for my personal playstyle.

Yeah, I found Thief frustrating to play in beta. Too squishy.

Learning to move, dodge and properly use situational skills, along with a build that suits me, really made the difference. It's now one of my favorites and a friend, who plays a Warrior, often is disgusted at how much more survivable I seem to be on my Thief than he is on his Warrior. :)

necro i didn't like it on start but now its far my favorite from my 5class's, (4L80 and 1 L55), on opposite i liked eng on beginning but now i cant play with him, the whole class sux, no wonder theres so few on WxWxW, its the only RNG class in this game and basically its the worst of all no matter what build which skill, its the worst , period . i tell this cause with my ranger, necro or guardian i can do very well on WxWxW , but eng its pure crap (i refuse to play more as grenadier, its painful boring after 1 full month playing it).
Example: when i need hurricane i get juggernaut, when i need stability i get stealth and so on , in a day of bad luck you get completely frustrated

During BETA, I mainly played the ranger (which I barely play now - my first toon to level 80 when the game went live).

I tried the Mesmer, and at level 4, I could not kill those skales (that regenerate health)...  the lack of dps and knowledge of how to play the mesmer frustrated me...  I stopped playing the mesmer for a good while, then came back to it.  It's been a few months now, but once I hit 80 - the mesmer became a lot more fun (my 3rd favorite class) and I use it for almost everything.

I barely gave the necromancer a chance during BETA... just didn't enjoy it... tried a few times.  Decided our guild needed a necro for dungeon running... and just like with the mesmer - I reached 80 a few months ago, and now it has become my favorite class.

ranger -> started as my favorite, now not so much anymore

mesmer -> started as my least favorite, now my #3 favorite

necro -> couldn't get into it, now my #1 favorite

#2 favorite is the guardian, if you were wondering :O
