Glass Cannon is totally worth it, and so is Lone Wolf.
No, that's mathematically wrong.
Sadly right now, once you get to a decent level you max your Start/Recovery/Turn APs so the boni you get from Glass Cannon / Lone Wolf become invalid.
Right now they are not worth the sacrifice, at all, from mid-game onwards there is no difference between a normal character and one with those beside the fact the latter dies much quicker.
They need change to be worth taking.
