This makes for a much more interesting fight. I had one combat style which required a parry, which was then the prerequisite for another style, and then yet another. In this way you can sometimes string together a nice looking combo for huge damage. My only complaint here is that these are often difficult to pull off, but considering the amount of damage I can inflict with a successful one, I can see why. Mages have a nice selection of spells to use where Archers get progressively stronger critical shots.
Some classes also have pets to help out in combat.
Druids summon animals and other nature creatures, Cabalists summon golems, and Hunters can charm animals to help them out. Heck, there's even cool assassin type characters that use stealth, backstabs, and poisons to eliminate their opponents. Each class fights a bit differently, but once again, they're all fun. Some new Guiniverse Boards have been opened as well. Here's a well rounded DAoC update.
