I can understand if cryptic doesn't want us to be able to respec every power we've chosen. Maybe we should only be able to respec powers that are 10 levels old. But with all of the other things going on besides powers, there's a lot of chaos in the powerhouse, in my opinion.

We should only be able to respec the last few power choices, to keep inside this 10-levels-old limit.

Advantages/Ranks should be in a seperate category. There should be a flat cost to unspend all of these points.

We should be able to respec our most recent superstat selection at least.

We should be able to respec all of our talents.

I think that would help a lot. It seems that the whole "10 limit respec" seems and feels restrictive at times because of the different point pools all being lumped into that same limit.

If they were broken into separate categories (like when you earn the points to spend ;) ) it would seem to keep people aware of their power purchases, but still undo more than two powers and a handful of talents/advantages.

Probably not 10 powers, since you can only get 14 total, but the devs should try working this system internally and see how it works.
