Ability concept ideas

1. An ability close to Yasuo's wind wall in the way of interacting with enemy skill shots but in a matter of once shot at the wall it returns in the direction of the opponent and can damage both teams depending on who is hit. Also if this ability is a on click shot sent through the wall but still a projectile it would be returned directly to the caster and deal to them whatever was shot. An example of this would be if a Ashe sent her ultimate through the wall it would be sent out in the exact way that it came and whoever is standing in the area of the shot would be effected regardless of team.

2. Another concept would be a passive that when you stop moving for 3 seconds and haven't took damage for 5 seconds your health regen and mana regen are doubled but as a negative once this takes effect all ability have a go on a temporary cool down so that after you break the passive your abiltys are on a 1 second cool down as if your slow after waking up or along those lines
