Got it on Bairdotr, after playing with it for a while, still seems good to me, just not like "lol let me cast 5 spells this turn and cc everyone." To me, it's more fun when something doesn't trivialize the game. "Just don't use it," you might say, but I like Glass Cannon conceptually. I want to use it, and I'm glad I can now without making the game too easy. To each their own.
I think it's probably still a fairly optimal talent on a ranger that you keep far back, especially if you have a couple warriors and a lot of CC.
