Kindred

Considering she is only truly effective in one role and she got ult nerfs, it isnt to much of a surprise. Also, I don't know about you but I hate how I have to run around the map to get stacks that might have alreadt been denied, especially when that is what the champion is all about.

She's designed to jungle but lately I've seen her have more success bot lane than jungling. She seems to work especially nicely with Janna, the shield gives her very strong trading in lane, and the ultimates work well together; overall this is a very annoying and hard to kill bot lane, hard to shut down if they start snowballing.

Her ult is a very important part of her kit and lots of her value is tied to it, but imo outside of organized play Lamb's Respite can't be used to its full potential (especially since she's relatively new and people aren't too used to play around it on their team). She's an ADC with Bard syndrome, tailored for high elo/organized play but not that good in unorganized, low-to-mid elo play.

Also, champion popularity is heavily tied to what the pros are playing, and she's too knew to have been played in the LCS/Worlds. People don't jump on bandwagon until pros tell them it's OP.

Her passive not being capped against Baron was the only reason to pick her, and that got fixed a month after she was released.
