Tips to play kindred:
Positioning your W:
Position your W with care. You have to acknowledge that your Q resets alot of it's cooldown when used inside your W, so to maximize the amount of Q's you can use, place your W in a way where you can fight while still inside it, or in other ways depending on the situation.
E mark:
Mounting Dread is an execute. Meaning it does extra damage to lower health champions, with the hp execute threshold scaling with your crit chance. It also slows for 1 second, so use it wisely as it has a high cooldown. Is your opponent running away? Use E to get a few extra hits in and maybe execute. Are you going against a champion you're currently even with? Use E early to maximize your damage output, or to execute if you feel safe you wont die before you get to use it.
Wall hopping
You can wall hop small walls with your Q. It is a corekindred mechanic you have to remember to play the champion to it's fullest. Here is every wall you can hop (outdated map but alot of the wallhops kept unchanged)

When to use your ultimate? Lamb's Respite

In low elo, don't waste it on teammates that cannot do anything to help in a long extended fight, but always save people when you 100% can and there is no chance they still die even after it. If you're confident enough you can ult them to get out of bad situations/flip them up. A good combo is Dance of Arrows > Flash > Lamb's Respite. This combo can quickly jump towards someone to save them. Flash > Lamb's Respite also works.
Tricks to do on kindred:
Believe it or not, kindred actually has a combo. To use it, get your opponent low, use Lamb's Respite, get them to low hp, use Mounting Dread, hit them twice, wait for ult to end, and finally Q auto out of your ult as fast as possible. VERY effective and VERY good combo. It makes it so you instantly execute them as they get out of your ult.
Another trick, that alot of junglers can do, and so can kindred, is level 2 invading. Take your red and go instantly into enemy blue. If it's despawned, they're at their gromp, and play to kill them, if they manage to escape, just steal the gromp and be happy with it. It is recommended to understand that you can get invaded on your blue after this play. So have something to back that out for you, have it be your blue being warded early or you backing after the invade and going instantly to your blue, to minimize chances of being punished.
You can also kill people from far away with Wolf's Frenzy. For an example, a low hp laner under their tower.

Kindred's marks are what makes kindred, kindred. Plan to play for these marks as much as possible as they are worth a LOT. You spike at 4th mark the most, followed by 7th and 10th marks.
You can manage your marks by understanding where your next mark is gonna spawn and killing one of the markable neutral camp options so it spawns on the other one.
A tip for killing marked champions: mark them knowing you have to kill them after 8 seconds only to get your mark, so try to come from behind them or pre-mark their lane if you plan on ganking it. Also, at the start of the game, remember the always mark enemy jungler until you get to do anything.

If games get stalled out of enough, you have to understand, as much as this champion is strong, against some comps it's impossible to completely solo carry against. You can still do your part and hope your team helps you play the game, but if you have 4 inting teammates, there is sadly nothing you can do, so if you want a solo carry champion for every single game you play, kindred is not it.

Any other opinion is wrong or you're a furry.
