For me, jump is a pain in 3 different scenarii:
1. It shouldn't be allowed as a bonus action in combat to disengage but as a full action.
2. When I jump with one character, the others should follow if they are chained to the character jumping without having to take them there one by one.
3. When I want to jump back somewhere and the other characters are on the way, they should move aside to let me jump without having myself to place them properly each time.
Jump should either cost an action, or cost movement... but it should not cost both actions AND movement.
