I'd like to see more severely potent enfeebles that are short acting but extremely devastating to the mob instead of debuffs that you're unsure if the effects are even making a difference. These debuffs wouldn't be very rarely resisted and would be extremely potent i.e DiaIII/BioIII/Flash/Stun type spells. Make Gravity 2 short lasting but have extremely potent evasion down. Keep grav1 for movement speed(not like its difficult to keep grav1 up with haste/fastcast gear, the recast is fine)
