Here is a solution for you, play a necro. See if you can get to 30 or something, just to get the jist of how hard it can be.. Plus you can learn how to fight them, think an enemies ability is ridiculous, then play and use it from the other side of the spectrum, when your necro with mastered sleep spell still fails more than half the time seemingly and soon as you fail you get bash/tripped/ or just your ass handed to you... then say sleeping is overpowered. As often as the average necromancer/thief gets tooled in fights with fighters, the few times the jack/sleep does land, its like its so much worth it being able to land all those abilities, but yeah, necros have it hard enough, plus they just tweaked sleep so its even worse.
