Right, and it needs to be updated, if not to a set time, have it based off of stats (which would take more work as they are currently re-working stats)... But trying to keep it cast on everyone is just plain annoying. With the mp regen update, MP isn't something that is hard to come by, thus saying that we have to cast this every five minutes to balance out MP isn't 100% correct...

If anything they should adjust these spells to add that level of buff to the players and add it new buffs that last a shorter amount of time and with different conditions, like channeling type abilities (aka the Barrier spell in the opening of LL's story) and other abilities that generate hate and drain MP...
