Kindred is typically known as a jungler and thrives in that role, and you can pretty much say that she was designed to be a jungler. However, that doesn't mean she cannot play another role, because he kit and current build fall in line with that of a normal AD Carry. When I think of Kindred ADC and try and compare her with other ADCs, I think she most functions like a more aggressive Vayne. She has a great dash/attack ability in her Q that offers her great lane mobility and is great for dodging skillshots to prevent engages and giving her an opportunity to counter. Her W has great sustain for her to heal in lane after trades, as well as her W being its own trade tool. Her E is great to use against squishy ADC opponents for an easy execute in 2v2s.
One of the big issues regarding ADCs themselves is their own survivability and how if played incorrectly, it can lead to them being obliterated and one shot. Kindred offers a counter to typical assassins that are conditioned to perma-diving the AD Carry with her ultimate and mobility. If used correctly, your ultimate will prevent any assassination attempt in teamfights or if you are caught out, and can, in some cases, give you a chance to assassinate the assassin.
When I speak to people about Kindred ADC, the most frequent criticism I hear is that she has low range. She has a lower range than a fair amount of ADCs, but her range is not as short as most people make it out to be, an ontop of this, if you play her correctly and well, you will be utalizing your passive to increase your range, which helps soldiify her as a 1v9 hypercarry in the late game.

Playing the lane with Kindred definitely comes with some practice, because you need to know when to commit with setting your E off. For Kindred, you will want to play passive until level 3 when you have each of your abilities. For your first level, you just want to farm, and with your mobility on your Q you can easily avoid danger. Level 2 you get your W, which allows you to trade and gain a lot of sustain, but avoid all ins at the very least until level 3. From level 3 on, you can begin to play the lane. Kindred works the best with an engage support like Leona or Naut, because their stun allows your to quickly get off your E and drain the enemy. Most players you come against is going to disrespect your E's damage and execution properties, so it's important to understand your own damage, since you have the advantage of your opponent not being sure of how to play against you in lane.

Passive stacks are quite important on Kindred, and are normally what separates a good Kindred from a bad one. Ideally, you want to be skirmishing your lane and getting kills of the marked enemy botlaners, as well as providing support for rotating to the initial scuttle crab for an easy stack. If played correctly and into the right matchups, you should be able to end the laning phase with your 4 initial stacks.

Kindred operates just like an AD Carry would in teamfights, being the backline and doing as much damage as possible to what stands infront of you. Because of Kindred's mobility, you do have pick potential in teamfights if there is an enemy low you can either Q onto them or galeforce if you took that item.
