Perfect World Entertainment has spent a fair amount of time talking up their upcoming PvP-focused game, Battle of the Immortals. The game certainly looks gorgeous, but we've only heard bits and pieces about how it will actually play. The most recent update, however, certainly provides a fair bit more information on how the game, as it details the game's classes -- Berzerker, Heretic, Magus, Slayer, and Champion. Each class is given a brief writeup of their strengths, weaknesses, and preferred opponents.
In no particular order, Slayers deal a mix of physical and magical damage at close range but have next to no defensive abilities. Heretics are a combination of priests with more sinister magics, dealing damage and healing as well as inviting a few obious comparisons. Magi (or maguses, if you prefer) are... well, okay, they're kind of obvious. Berzerkers have an errant "z" in their name and focus on dealing out physical damage at the cost of some defense, and Champions wield a weapon and shield to be all but indestructible. The classes seem set to provide a fair mix of the usual "holy trinity" mechanics and PvP skills, so take a look at the official preview to get a clearer picture of what you might want to play once the game goes live.
