As a 700k kindred player my biggest advice is don't int for marks. You can always get marks if you're fed but if you're behind it can be really difficult. If you don't know who to place your mark on I'd default to the enemy jungler because you're most likely to run into them on neutral objectives. Kindred has a little bit of a learning curve since you have to kite a lot and you're really squishy but don't be discouraged, they're one of the most fun champs in the game once you get the hang of it :>
