Your choice of class is important. I could end this post with that sentence and it would get my point across just fine. It’d be a little obvious and contain no support, but it would be true all the same. In the top MUD Achaea, by Iron Realms Entertainment, I play Raslazel. He’s a Sentinel. Sentinels are like Druids (who can morph into animals and interact with plants), except they are not tied to nature in the way that druids are. They set traps and use their metamorphosis in conjunction with spears and throwing axes to overwhelm enemies. This style fits Raslazel perfectly while the purpose that joining their House gave him was just what he needed.
I told you that because it’s a good example of how to choose your class. Choose something you think will fit your character, as you envision him, nicely. If you decide to change later because that’s just not working, you’re all the wiser for it. Many people choose their classes willy-nilly without considering their character and wind up in a group of people they don’t get along with as a result. I’ve made that mistake, too. It’s important to decide carefully.
