Kindred (A inconsistent jungler at best)
I absolutely love playing Kindred, but I absolutely agree she is INCREDIBLY tough to get off the ground. This is compounded by the (what seems to be consistent notion) that your team-mates very rarely assist you in getting an jungle mark because -- no shocker(!) -- they don't want to fall behind in CS.
Considering a jungler's main goal is to 1) farm camps and 2) gank lanes, having to travel across the entire map to get 1 camp that you have to rush takes away from both of those things! And imagine getting their as soon as you could to see it has already been taken and you've just wasted the last minute trying to grab air. It has a fair bit of highly inconsistent jungle play.
I don't know what they'll do in the future with her, but some temporary changes that could make it worth while would be... 1)Remove enemies mini-map sight of the mark, only allow them to see a marked creatures face-to-face. 2)Add in a minor gold benefit for obtaining a marked camp (I don't know the numbers, obviously, but say you get an extra 20G+ for scoring a marked camp.
