About the new game mode (Overcharge)
I'm noticing that there is what I would consider to be a toxic/unhealthy way around avoiding overcharged enemies in the way of constantly vent jumping over the same two vents back and forth. I don't know if my comments will make a difference or if there is even time to make a change to them yet but I think it's not quite healthy for the mode when someone can just jump back and forth non-stop until the timer runs out.
I know it's supposed to be a fast-paced mode but it makes it feel too frustrating having to deal with that. A simple solution is to put something along the lines of a 1 second cooldown on the air vent (champion specific) so you can't keep the infinite cycle up.
We already have champions like Tristana, Corki, and Ezreal who can blink themselves and flash as is so I think it would be fair to make a small adjustment like that.
