yes, but think, if the unit is not attacked and woken, at level 3 that unit is out for 60 seconds. It actualy is meant to stop spells like BBV and starfall. Sleep is used on fleeing heros that are weak. even if woken, it can buy time to catch up and kill it. with hex, you can still run away. and 6 seconds with it still running isn't to helpful.Originally posted by Intel Zero
Hex is good because you can attack the unit once it's hex'd, whereas sleep, you cannot attack the unit. No damage is given during Sleep.
