I've played more games on kindred than any other champ. I have one question how do you play him?

No I don't mean how do you personally play I'm asking what is the proper way to play kindred I'm an s4 scrub playing a rather complex champion i know ,but maybe there Is someone out there that can show me the way to improving. I understand everything in the champions kit but some how fail in execution of using it like ganking and counter jungling for marks. I don't what makes a good time to collect a mark and a bad time to collect a mark and that's why my confidence with the character is so low. as for runes i usually take dark harvest or electrucute into sudden impact eyeball collection into ravenous hunter then go down the precision tree for bloodline and coup de grace. Her ult is one of the most game changing abilities in the entire game but i usually refrain from using it in fear of messing it up. i feel like I'm just bad at the game please help Q_Q
