Jumping absolutely needs to incur attacks of opportunity. It's frankly ridiculous that they deliberately made it not. If anything, let the rogue keep the non-AoO jump, everone else gets bonked in the head if they try something as stupid as leaping away from someone swinging an axe at your back.
Pen & Paper Rogue gets Cunning Action on 2nd level which means they can Dash, Disengage or Hide as a Bonus Action. They should probably get that in the game too, instead of letting everyone do that.
I suspect that implementing an "action economy" that mirrors the D&D 5th edition ruleset more closely would be a big benefit to the game but I don't know, maybe they already tried that and there's a reason everybody gets to have Rogue abilities. On the other hand, there are some very basic misconceptions in this game about the nature of D&D 5th edition mechanics that makes me worry they just haven't read (or understood) the ruleset they're basing the game on...
