said by McBrain:This was what really did it. BoA's made the gear more comparable, but XP in BG's and a separate queue for having XP turned off really did it. Most people didn't twink toons to be competitive in lower level BG's. They did it to rack up 50+ killing blows and no deaths against toons in all greens or even grays and whites in the 19 bracket. Also, the splitting of brackets made it harder too. It was brutal to see twink 19's going off on toons level 10-12.
BGs giving experience killed twinking.
That's my .02
