The "WAR" acronym is also a not too subtle dig at WoW's more constrained PVP experience. I always write out Warhammer on principle.

As to the original post? I think it's a bit early to be deciding what Warhammer will always be remember for. For example, the famed city sieges - it might be so hard to break the stalemate that none of the cities ever actually come under siege, or you might get a situation where one side owns the opposing city so often that the losing side can't stand never having access to basic amenities and rerolls or cancels en masse. Public quests sound like a fun idea, but if the incentives aren't good enough high level players won't show up for the final round, and if the rewards are too good, high level players may overrun low level zones. The Lorebook may be a neat reward for doing unexpected things, or it may turn out to be a hideous grind.

I suppose people will remember how this goes down no matter what, but whether those memories are fond has yet to be seen.
