Support class is not fair, other classes buffs ideas

@RXYRP
They have some sort of speed limit for balancing. Octane pushes that limit.
Having a speed buff passive wouldn't be very effective for them.
However, the reduced penalty while aiming might be something, but that would really push Octane into meta again. He still sort of is.
I was thinking maybe something along the lines of give them Hover as a class perk. They can all go airborne quite easily, using Hover could give them an extra edge, until people start expecting it. Then it'd be the 50/50 are they gonna hover or not deal.

Assault:
Give them all painting enemies: When they hit a target, they highlight the target briefly for their team. Maggie keeps her passive as class perks have no effect in Mixtape. Maybe buff Maggie's passive to highlight for the team instead of only for herself.
I was also thinking another option could be extra grenades. BTW Fuse would stack 3, not just 2, while that class perk is in effect, still making him the ultimate grenadier.

The 50% you're suggesting is too OP. They'll never accept it because the value is so high. Reduce it down to the common 15% and maybe they'll think about it.

@Zulkiers Cool ideas
