Well I am 59 trying to hit 60 by running grinding profiles since I need the darn mount for BC and I notice once you have been grinding in 1 area for to long exp goes from like 340 per kill to freaking 25-35 per kill? Is this something new?
Well this sucks cause I have to change the profile every like 30 minutes sigh.
Since the worldfirst lvl 85 and lvl 90 (I think it was the same guy) "cheated" his wayup to reach that achievement, they wrote in a bluepost that this new mechanic is introduced to prevent this.
(The guy hitted the mobs and his guildmates killed them)
Thats why we have questing botbase. It could easy change the grinding zone, so the handycap reset.But they removed his achievement becauso of abuse of game mechanics.
So this might be the end if grinding as we know it.
Could use a questing profile instead? Worked fine for me in general (though the BC areas on the 1-90 mega profile pack sort of suck.)
