Agreed Hamster, the lack of time for debuffs from enemies to stick make paralyna and silena etc redundant.. Sleep is just right I think. And buffs to last 5 minutes at the most is a bit short. Shock spikes aren't so bad, however, they are extremely effective and quick to cast. Debuffs from CONs to stick is about 1 every 3 times too and I don't think Dark Seal makes much difference, they should up the odds a bit on that too so that Sleep and DoTs are more useful.
