Don't want to be disrespectful raptor since on most cases your points are valid but please ask yourself one question, an ability is too powerful in comparison to whom and what ?
Honestly for every 1 buff we get 2 nerfs and while i don't really care (since i refuse to further participate in blizzard's "fiasco") you should compare our skills and abilities with the other dps classes.
As for 1k tick corruptions, on live i have seen ticks up to 1100 thanks to T5 set bonus and strange 40/21/0 builds (800-900 on normal builds) and let me assure you that affliction still sucked overall.
Affliction will look good while levelling /acquiring your lvl80 gear. The moment haste gets into the equation every affliction build will become obsolete. Btw don't expect affliction viability to last an entire tier of instances, haste is everywhere across the boards this time.
Edit: Was about to write that Chaotic mind "thingy" was a very nice addition , but it seems they removed it
