Making someone evaporate in several seconds is fun, very satisfying. I do it live, turn on PvP, target some Timmy running with PvP mode on and BBQ.
What, you think wPvP is some sort of honorable duel of equality? lol. Attacking when you have unfair advantage and running away when you don't is all there is about forever.
Warmode does nothing new, people who choose to use it can't complain about getting ganked with unfair odds, if anything I think it's a tiniest bit more fair because at least you can't turn it on just like in example above and then drop it with simple whistle - you can only turn it on/off in Stormwind, so at least you commit, unlike now where you can turn it on in people's face - bbq them, then turn off and instantly drop timer with whistle.
People who will have Warmode on - tanks, healers, guys who can run away anytime like Rogues, OP duel specs and occasional n00bs who don't know better and will turn it off after getting creamed a couple of times, so I find it fair game to counter the actual threats with outstanding gear.
