Most ADC's might be useless, but try this...

ADC. Honestly, I feel like this has a lot of potential. A mage might do better when it comes to damage, but they still do magic damage. If you are a marksmen main, give it a try. Her R is basically anti-tower dive and when you bring ignite you can punish people who sit in your ult. Her Q is a dash that does % current hp damage, her W makes an area that reduces her Q cd to 2 sec, and her E is a slow and 3 hit burst. She is also a monster late game.

The downside to this is that you really are giving up early game as pre level 6 you are still a hunk of junk like all the other ADC's, but you can't be bursted down and you offer utility to your team with your R.

I might be wrong, but I feel like she out damages some of the mid game ADC's like and in the early game.

Might not be wise to try this in high elo, because her attack range makes it easy to get free damage onto her, but mid elo and especially bronze, where games go into late game anyway.

This may or may not be good, just give it a try.

TL:DR Kindred has utility and is useful vs a burst team. Extremely good late game. Very hard to gank and tower dive.
