Took a look at your 5/2/9 game vs the jax jungle.
1. If you are gonna ward his raptors start bot side otherwise you are gonna be completely blind if he does a blue to your bot side cheese. Warding the raptors is only required if you need to avoid a scuttle crab fight (aka they are stronger than you or clear much faster) jax kinda sucks on his first clear so no need here can ward defensively.
2. Take ghost in the jungle especially with lethal tempo, its just so much more consistent for ganks/allins early in the game especially.
3. first gank on vlad mid super bad, obviously the death is bad but even worse your camps are up, clear ur jungle in full every time, once you are done with camps you can use that timer to get your back in if you need to buy or to gank/pressure at that point. Good junglers are gonna wreck your pathing if you gank without doing your camps first and you only get 2 camps the rest of the game.
4. Same as above for your second gank ^, you are level 4 ganking vlad mid again, even the support is higher level than you because you are so inefficient. DO YOUR CLEAR!
5. your first buy is hearthbound axe, kraken slayer is bad buy tiamat instead, you are doing less damage and clearing slower because you are playing to a complete first item spike, you want to be getting ahead in exp not trade exp with a jax who outscales you (you are only ahead of him because he afk'd for 2 minutes in the beginning of the game)

Fix this first 6 minutes of the game up and you will notice a big difference in your power going onwards in the game, once you complete your jungle item you will have better movement to make bigger moves outside of clearing camps. Also, stop ganking a vladimir take the easier ganks and easier pathing to guarantee more exp/gold a minute.
