I'm not a viktor player however
Even though I know the reason for the nerf I can admit it was wrong to nerf viktor without a compensation buff so I have an idea:
Buff viktor so his Q does an AoE around the primary target of the AA(2ND Part), like gragas' buff.
That would fix his issue of being overnerfed on his laser and make him more interactive in waveclearing since he would have to go in range to AA.
Would reasonably buff viktor in a way that doesn't simply increase his damage and fixes the issue of being overnerfed laser-wise.
