I still don't have a true solid opinion about jump potions in this game, but it can happend.

I think the mentor system in this game very weak by the fact It not help once you reach the max level and have all your rotation. (something that should be good with the jump potions implemented).

So in this game mentor is besically someone that know the boss simple mechanics, basic PVP or simple crafting. And want to help new players that have no idea of what is going on.

And hire come the new player that use the jump potion, they will not be able to help in all scenario. Because they will miss some c boss mechanics and content. They only solution I can think right now is maybe use the mapping the real to lock the mentor not the clear so if they wanna become mentor they should do the dungeon for it.
