And now for something a bit controversial; i like the bonus action abilities Larian has added to all characters, Jump, Disengage, Hide and Shove. They make combat more interesting, with more things to do, this being a video game and not pnp speeding up combat by giving these options is a great choice. This could maybe even be added on to with a grapple and knock prone ability (not necessarily as a BA), giving more tactical choices to melee characters. But, a really don't like dip, it doesn't feel right. Besides that jump and disengage should be separate abilities (both still BA) to avoid the "bugs bunny" effect, the AI disengages normally, so should the PC's.
I'm one of the few people here who will fully agree with you on this. At first I was like, "Rawr, this is not according to the rules! I shake my fist at you!" But the longer I played, the more I came to realize, "This is actually more fun than it would be according to the rules, and must especially be so for people not familiar with D&D." Which is probably most of the people buying this, honestly.
