(Disclosure: this is a copy/paste from another post I made, but I feel it's going to get buried/ignored and I'm really curious about what more experienced Black Mage players think of it.)
What if Sleep and Freeze applied debuffs to a target when their Control effect ends or is resisted?
Like Sleep decreases auto attack speed, skill speed, spell speed by X% (Effect Named "Groggy")
And Freeze causes the target to take extra damage from all sources (Effect Named "Fragile")
It occurs to me that Control is really the utility of the Black Mage (like how Recovery is Red Mage Utility) given how over the top powerful Sleep is on paper. And DCUO had a neat trick with Control abilities where they also provided debuffs for times when Control was immune or not needed (like a boss fight with only one target). So If I took those concepts and applied them here, it might work.
No one would really care that much if you toss a sleep into an AE pack, they'd break immediately and now they're all debuffed so it's still valuable. And if you were using kill priority single target it works just as well.
Thoughts? I'm genuinely curious.
