i actually like new kindred a lot
i don't think they follow the power-curve riot intended (good early weak mid gr8 late, they're bad early, then pick up mid and becomes great late) but, aside from not being able to fight anyone early game, they're a pretty fun experience. it's also nice that not getting stacks isn't so detrimental; if it's a counter-pick jungler like lee sin, lee sin, or lee sin you can just farm and wait to get stacks once grouping happens
i think they need a little bit more than what they're getting on the pbe (2 ad lul) but their winrate might fix itself naturally, so who knows. she's pretty strong with a crit build once she has her items, though
