I wouldnt boost as it will just be the same 70 to 80. I would stick with it and see if it improves. I'm also leveling an AST and I have the whole healer anxiety thing, but the more I play and get used to it, the more fun I have.

I'm no where near a great healer but as small as it may be, you feel good when you get comms, and I got three the other night when I thought I was terrible. No one died but I always over critique what I could have done.

In the end, most people are cool if you just mention you're still a leaf in regards to AST.

Good luck!
