I stand corrected, however excessive numbers simply aren't fun, and with how things grow exponential over time, it just becomes more and more of a problem. The results of this poll seem to be aligned with my belief that most people don't like huge numbers, just big ones, and it's worth feeling "nerfed" (I don't, it's all relative) for a short time.
And with how things are at lower levels, they won't need to tweak the over all numbers, just this current expansion. The curve right now is really odd, near the end of WoD while leveling you're doing like, maybe 10k? then you hit 110, and you're rocking 800k to over 1.5 mil depending on the fight.
