As many other people have stated, the trample skill is not very practical on controller.
When you use it, your character does not go to the direction you pointed to, it goes to the closest enemy on screen, and stops if there are no more enemies beyond.
This limits the functionality as a movement skill and as a cc escape skill. For example, I have been killed by the echo of Lilith attack that sucks you in the pit after trying to escape from it with trample but getting redirectioned to the boss which is usually at the middle of the attack area.
It should move to the direction you are pointing to with your stick regardless of the enemies around, and should not stop until you release the button (with a limit ofc).
