I'm loving the Koggy changes
I'm a bit worried that it'll push TanKoggy over the top (BotRK into Wit's, follow up with pure tank items as needed) assuming the base damage on his W isn't going down to compensate for the bonus AD ratio they're adding (still haven't seen exact numbers on the new W ratio).
That aside, I'm pretty happy with the change.
Previously Vayne out-classed Koggy on the tank-buster side of things while Jinx had him beat on the long range auto-attacker front due to her superior control. With these new changes, Kog's niche will be very clear. He's the immobile face-melting monster. Want absolutely punishing single-target damage from long range and you're willing to give up any degree of mobility and utility? Then Kog is your Voidpuppy. This will leave him VERY distinct from Vayne and Jinx, which is all I've been asking for ever since Jinx was released.
So Vayne is for murdering tanks and being highly self-sufficient.
Jinx is snowballing in battle whilst providing moderate peel for yourself.
Koggy is for murdering everything if he gets left alone for the duration of his W.
Nice show, Riot.
