You are correct the overhealing thing is one of my problems. The only heals I should be spamming according to what I have read today is Diagnostic Scan and Slow-Release Medpacs to keep energy up and Upper Hand at the ready.
Another example why it is me and not Lynk that is the problem. All those big heals are pulling aggro too fast. I'm all for blaming Lynk for any and everything, but in this case it is me.
