Yeah I guess it's a choice between the elven racial+tactical retreat and glass cannon. I have found glass cannon to be ok for ranged characters, provided that you have good positioning (tactical retreat helps there as well).
I was so starved for AP, that I decided to try Glass Cannon... What a disaster. Any CC they have is thrown at you and only you. They
know that you're running Glass Cannon, just like how they know Fane is undead instantly.
It's just awful.
