A suggested Vel'Koz Q change
Going to shamelessly repost from a thread on 4chan.

Velkoz is an interesting champion for us to adjust. We wanted to keep his identity of a high damage mage in tact, but feel his kit isn't strategic enough. He has 4 skill shots, and each one deals big damage and builds towards his passive while offering little utility outside of that.
we wanted to make sure that like right now, Vel'koz's emphasis remains on damage, but wanted to make his kit slightly more strategic while also making it more mechanically intensive.
to do this, we felt the largest change would be to Plasma fission, his most unique skill. As it is now the dividing blasts from Vel'koz's Q feel redundant, since hitting enemies head on yield the same results as hitting them with geometry
to remedy this, we've made the primary and secondary charges work differently. Hitting an enemy with the primary charge will cause an 85% slow to improve its ability as a kiting tool, while the secondary charges deal 50% more damage, 75% more if the ability is activated Prematurely rather than it reaching the end of its range or hitting an enemy. This will encourage use of geometry when poking in lane. If all three charges hit an enemy it will automatically process the bonus damage of Vel'koz's passive regardless of stacks. We feel this adds several dimensions of play to using Vel'koz's most unique skill and will make him much more of a spectacle.
I think this would be an excellent idea, though with less base damage and/or AP scaling or a much smaller damage bonus or both of course. This would give an already fun and good champ deeper strategic depth and mechanics, on top of making him even more fun. As a Mid Vel'Koz main I'd love to see a change like this, but of course with tweaked numbers to make sure it's not blatantly OP like in the CP.
What do you guys think? Does anyone in Riot think this could be an interesting idea to consider for future Vel'Koz changes? Or would it be potentially devastating and make support Vel'Koz too powerful? rito pls
