Do you think the Viktor changes ultimately made him healthier?
as a recap;
Viktor is supposed to be less bursty and more sustain damage, E has a longer delay and R now ticks every 2 seconds.
I've been spamming Viktor since the rework hit, trying to get a good feel for how he plays now. I don't think this change has made viktor better for the game. the arbitrary delays added to his spells now require them to have obscene base damage and scaling in order to feel good; this makes him very frustrating for anyone caught by CC, or at any point after Viktor buys a rylai.
these changes didn't accomplish what they wanted either; Viktor is still a nuke mage, zone control comes at a not-close second. the best plan of action is still almost always to dump your entire rotation on closest squishy enemy; but now you have followup with your ult's second tick, which gives you, I would argue, unfair presence in teamfights for someone who just deleted the enemy carry. worse, there's a complete lack of clarity with his ult; the lazy VFX added to its ticks is impossible to see in busy skirmishes and barely visible otherwise, so it seems like people suddenly lose fat chunks of their health for no reason.
now that he's back to having powerful, safe waveclear on top of all of this, Viktor is no doubt going to see a lot of play at higher levels. It's likely that he'll end up drawing nerfs, and for good reason; he's too powerful. I think I have justified fear in that he'll go to the same place Mordekaiser and Skarner are in after this, where a combination of numbers and lack of satisfaction put him in the dumpster and ignored by Riot.
