I tried Glass Cannon on my ranger in one playthrough, to give crossbows a use. It is quite mighty even without a stupid ap build or using invisibility (a skill I never even buy). I always invest in Wits and I mostly go first with the whole group.
However, in some important fights my ranger was out some turns, despite positioning and so, while for normal fights the talent is not necessary. I'm still considering wether to take or not. I plan a Ranger/Summoner, and Glass Cannon on such a sleepy class as Summoner might be ok, it does not really matter wether your Summoner is in the fight or out because he is rather weak anyway (I'm exaggerating a bit, ok), but you can summon incarnate, buff and apply oil the first turn with 6 ap.
How will cc from surfaces work in the release? If you stand in blood and the blood gets electrified, do you get stunned?
