Sheffy, excellent list.
The top two are my biggest concern atm, especially now since the latest patch.
The healing aggro is insane. I have developed a style of playing at alien raids, heal and run! This isn't ideal though. I know people die more due to me running out of range so often. I just don't see why healing one person draws aggro of every alien there. I would like to see this calmed down a bit.
Higher team heal would rawk! As a result of the healing aggro at alien raids, I have been using Conglomerate Health Plan again. I have to say, as a 220 doctor only healing 600-1100 a cast, it's pretty pathetic. It doesn't have to be an incredibly high heal, but at least 4 times that would be nice.
Now I have an issue with something that was not mentioned. The alien doc perk line Embrace isn't all the great. Why modify MM without BM? I mean maybe back in the day before symbiants I could understand this. My BM was always a good deal higher than MM, but with symbiants I am completely balanced in those skills. (Actually I have 4 less in BM.) As a 220 doc, Embrace is almost completely useless to me.
