He's in an absolutely horrendous state. If you want your E/ult to be viable damage sources you need to invest in
as a first item, which is a huge kick in the teeth now that they completely gutted mana regen as a concept.
He feels extremely counter-intuitive to play because logically, you need to upgrade your
for augments, but you need
in order for your E augment to even be useful, but you need something with mana sustain in order to stay in lane/on the map to be relevant. He's in a position where he is absolutely gimped until at the very least 3 items (
/
/(

)), and this isn't even taking into consideration the cost of boots as well. But what do you get first?
If you get mana sustain youll be able to stay in lane/on the map but lack damage and wont be able to reliably utilize your E/ult.
If you get Rylais first youll be able to utilize your E/ult to greater effect but wont have the mana/sustain to stick around.
If you upgrade your hex core youll have the utility of a speed boost and/or your aftershock but wont have damage OR mana/sustain.
Theres no right answer for Viktor at the moment, at least not until the 30 or so minute mark, at which point he will hopefully have access to enough items that he can start to do his job. Yet even still, he needs a team composition with heavy AoE CC to be able to fully realize his true potential in a team fight, so if you don't have a team built around you, youre STILL up shits creek without a paddle.
