To be fair, they're only going to break when you're using them
But I agree that they need to make it more obvious when something has less than say 10% CND left, the tiny icon by the AP bar is too easy to miss.
Quit the beta early and cancelled my preorder last night after a couple of "OMFG rage" moments in combat. Made the noob mistake of trying to use the mouse wheel to change weapon, ended up stuck on the stupid wheel, push Esc to get off it, oh look, map screen... *you are dead*, then about an hour later, push G for grenade (you know, like every other game ever) "would you like to wave or dance at the nascent snallygaster?" ... *you are dead*... Argh!! Never mind the frustration of inadvertently holding down the melee key for more than 4ms and blowing yourself up with a grenade instead of punching that ghoul in the face... Broken, broken, broken game.
