The only tips in this game is fight when you are outnumbered your opponents.

As a witch hunter lv27, you will never able to win 1 vs 1 with a Destruction tank even  2-3 levels lower than you. In this game, there are food chain theory, A beats B, and B beats C something like that.

People playing Orders are free people with free will and most of the guild claimed themseoves as casual, friendly. And I never seen a Order guild use teamspeak/ventrilo or other voice software in game. Destruction may used teamspeak to play in the game and they are limited freedom in gameplay.

If you want to make a uber guild, choose Orders, your guild would be dominant in Warhammer.
