Trundle
Jungle clear:
Logic, hit the big one with Q while attacking the small one, than finish the big one ( for each camp )
Q+SMITE combo
Use the W in jungle clear
Use the E only if you are too low and u are going to die in jungle. And can u add something that Use E if the some enemy is coming near your jungle to steal it? ( for example enemy invade, i don't know if that is easy )
Outofjungle/toplane
Auto Q each time the enemy is in range of Q without having to press Harrass combo.
Combo: W E R Q spam Q with basic attack reset.
Escape:
Use R to escape if u are low ( let the user put the heal to do so, for example 10% 15% and the enemy is chasing you or if u get ganked ( let the user choose to use that escape mode if it's vs 1 2 3 enemy etc )
E
The E need a logic. If the enemy is near a wall , knock up the enemy and close him to the wall. If the enemy is not near a wall close the enemy away from towers. If no tower, no wall force the enemy to choose the pat near your ally. For example he can go left of right. From right is coming one ally , from left there is no one. Use the E to the left so he is knock up and forced to go to the right or lose a lot of time.
