As Bioware seems unable to implement dual specialization trees anytime soon, I decided last night to reset my trees and go for full healer.
This is a big difference theoretically and I did it so we can much more easily do Hard Mode flashpoints and hopefully Operations.
We'll test that in a HM soon.
Also, Crash dinged 50, so we have one more level 50, and this also makes teaming for HM easier.
It seems that I can reset back to my normal setup without paying too much, at least for a while. Not sure how it works exactly.
