Dance of Arrows
Not everyone can handle the squishyness of Kindred in jungle. However, he also makes a great AD Carry.
Focus on farming. Walk alot and stack up W's passive, that will grant you some additional healing. If possible, try to kill marked jungle creeps, but don't force yourself. Make sure your surroundings are warded - you're really squishy and vulnerable to ganks.
By now you should have the Botrk already. You can become a bit more aggresive, and try to mark champions on your lane. Roaming is still risky, but if you overpowered your enemies early, feel free to help your teammates on different lanes.
Make sure you remember about your passive! Every stack improves your auto-attacks, and even an assist on a marked champion grants you a stack that you really want. Pick enemies to mark carefuly!
Kindred's still really squishy, like most of AD Carries - but he deals TONS OF DAMAGE. Let your teammates engage the fights and DON'T CHASE! I know, that everyone wants the kill, but if it's not safe and enemy bruiser gets you, you're most likely dead. Mark the champion that deals the most damage in enemy team or is the easiest to take down - that will give you instant boost to your attacks if you only score an assist or a kill.
For now, Kindred is really overpowered - but still squishy. He (I keep saying he, even if he's \"they\") needs cooperation from his whole team. Tanky support like Braum, Leona or Nautilus are very welcome - snare or stun scores almost 100% sure kill for Kindred.
