@Meddler: Would this be a good support ultimate?
This would be for my high-mobility support Dancer Champion. It's a rough draft right now, so take it with a grain of salt.
Show-Stealer Salsa Dash/Blink to target enemy Champion and steal X% of the target's AD and AP for a limited time. Within the next few seconds, you can recast this ability to dash to target allied Champion and transfer the stolen stats to it for a short time; if you don't recast within the time window, the stats are lost.
All stat modifiers decay over their respective duration.
What would this contribute? Well, say your enemy has an out-of-control Jax or other high AD or AP Champion on the loose. If you're willing to take the risk, you can dash in, steal a huge chunk of that enemy's offensive stats, and give them to your carry. But you'll only have a short window of opportunity to complete the transfer; if your enemy can stop you from doing that, you'll probably die and not give your team an overwhelming advantage, just a moderate advantage. Given the risk involved, it'd be ripe for some big play moments.
Good ultimate for a support, or is it suited for another class?
