You understand that just the fact that they used that as an example goes to show how clueless they can be about PvP and the metrics... right?
I'm not going to even go into the many problems about creating "balance" in MMO PvP... but it surely can NOT be done with mathematics.
They need to either play the game... of listen to an intelligent player base or G T F O.
You'd be surprised what can be done with mathematics. We're basically wizards.
Not that I'm defending the devs cause I don't think they could balance PVP if their lives quite literally depended on it, but of the 8 ACs, 7 of them have a rated viable spec, and I'd say their massive overbalance of classes via nerfs in 1.2 had as much to do with player QQ as it did metrics.
Again, not saying they're doing it right, but mathematics properly applied could help a ton with balancing. Most forum posters are dumb anyway. Wouldn't trust them to balance any more than I trust the devs.
