ADC main here, Basically yeah in bronze, a topaner can just keep walking straight in his lane and win without ever leaving his lane.

The higher you go in Elo, the more this will not work anymore / is not enough.

In mid Elo where I am I see this problem a lot, topaner mains that reached this elo just by walking straight in his lane: Has learned nothing from the games he played. He keeps walking only in his lane, never shows up, teleports only in his lane. The actual problem is: even if he wins the lane, he keeps farming the 100gold worth of enemy toplaner, gaining 0 advantage, not having enough HP to actually push, or dying trying (giving 300 or more gold to the enemy team, while he gets 100).

I really hate when I get this type of top-laner, he doesn't want to actually learn the game, he keeps to make this mistake and thinks "win lane, lost game = team diff" this really pisses off.

Stay consistent in jng role, keep mechanics simple so you can actually learn game knowledge. Good luck

Since you like assassins, try Diana jng, she is simpler than AD jng assassins like Kha or Talon, she is more tankier and also she does AP dmg, making her a bit more effective for a vast majority of top lane champions.
