How do you define a high end player? My clans has multiple players with 100+ level gems and top 200 solo and group records. I don't follow clan rankings so is my clan high end? Most of my clannies play consistently, but are far from the lifers everyone talks about as throwing the curve off.
What I do know is that zdps play has allowed many players to make gains far past the abilities of someone like me who has refused to play any form of Z toon. Even if 2.4.2 nerfs z play the damage has been done and has gone on too long. I've been playing since vanilla, but just by refusing to play z I will never get to anything equivalent to where z players are standing at now. I made a stance and no matter what I will never make up for not joining the heard and suckling the teat of z whore that the devs allowed to happen.
I await to see what will happen in season 7 with the new patch, but the game is forever cancered by the past 2 seasons of z mania.
