Rogue Buff
Rogue is already great so she doesn't really need a buff the way some characters do but this would make her so much cooler.
Could you please increase the duration of her buff steal timer by 1-4 seconds? Right now it is so ridiculously short, there's no way to hold on to the buffs you have stolen. You have to attack super aggressively which results in you getting hit. If your opponent uses a special attack the stolen buff expires before the animation finishes. It's just way too short to be useful.
Either that, or change it so that "touching" your opponent is defined as either hitting them OR being hit by them. That might work, too, though it would be less ideal.
