| >>I like a slightly modified version of the drain rate idea where only the one skill taught by that cyclic is affected and it builds up over time to being nothing.|
At the very least, cyclics teach 3 skills. However, this leaves it squarely in the "If you're not constantly running a cyclic, you're doing it wrong" problem - Everybody would run around keeping a cyclic going with no reason not to.
The only real mitigation to THAT issue would be for the haze's duration to continue getting extended even after it hits that steady state. If you go for 2 days without dropping your cyclic, you're going to have a bad time training your magic skills for a while.
But then, that just encourages you to leave yourself logged in and AFK to drain that penalty, which isn't a good thing to encourage. You'd also have people that royally screw themselves over by leaving it on too long and then assist when their augmentation training is in the dumps and they don't know why.
See how it gets a bit messy? :G:
