Message to Sven : you like to see a character pushing to avoid AOO because you don't like melee character (AND probably because you are not playing your games for hundreds of hours !)
It is a huge tactical issue. AOO are a CORE feature of what makes melee character interresting. You made a GREAT step forward when you decide to decouple jump/disengage and make it an action BUT you still have the same issue with shove !
Not 100% sure what you're saying here, but shoved characters do not provoke attacks of opportunity, the same reason spells like thunderwave moving enemies around won't trigger them either. Characters have to move of their own volition (or have to be manipulated by a mind altering effect like Dissonant Whispers) to provoke opportunity attacks.
If the enemy AI is abusing that concept (like using shoves to wake up sleeping allies, which from the looks of it is no longer happening as of this patch), then yeah, it's really silly. If the player is doing it... Eh, their choice, not worth getting worked up over.
