Perhaps we could make change of weapons and drawing weapons each an action, for balance. Combat is much too fast and not enough TT-boring like.
Or not. Perhaps it should stay as it is. If you don't like shove, don't use it. As the AI indeed uses shove (I felt it several times) it may be a problem for some TT-people, but then just stay away from edges. Shove is already nerfed a lot and frequently fails. I shoved 4 times with my current Barbarian till lvl 4 and 1 time it threw a small goblin down (to the spiders), 1 time it made the target prone and 2 times it failed.
Same as barrelmancy. I did not use a barrel a single time in my last playthroughs, the only exploding stuff is when the dump little dealer blows herself up by some actions.
Making jump an action would be ... a bad think for melee based chars, don't do it, Larian.
