voli in his current state NEEDS a major nerf.
-He is a tank, high Dps, high utilty champ.
-his ABILITY does normal damge(this is absurdly good and he is the only one unit that has this and I don't know why(yes i know Rengar, Draven, but these are just buffs- they are not giving them the ABILITY to shoot lighting through enemy teams)).
-there is NO counter to a volibear with rpc since his damage is normal and not ability like it should be.
-rfc enhances his ability jump range.
-his ability does not only make his normal damage strong, but also applies them to multiple targets.
So yeah make the first unit get hit by on hit attacks, and everything after that is an ABILITY and therefor should just do ABILITY damage without on hit effects. I dont know who came up with the stupid idea of making his ABILITY using on hit normal attacks on every unit that gets hit by his ABILITY. Basically make it a stronger version of statics.
Even if they nerf him too much: Its better to have an underpowered unit than having an overpowered unit, as an underpowered unit does not break the game as much as an overpowered unit does.
