The thing is a lot of the changes you just mentioned were mainly NOT HC. Alot of that was the devs from live, Paragon Studios. And softcapping was happening during that time. I remember numerous discussions and arguments abut the game being poorly balanced and too easy even back then. This isn't new.
EDIT: There used to be posts after posts of people ALSO arguing that Controllers, Defenders, Doms, support needed wholesale buffs. They didn't and they still don't today.
There are a few sets or powers that need changes but nothing as radical as some are alluding to about Support in this thread. This is coming from someone who mostly plays support sets. (if I didn't make that clear before about what types of toons I play).
