Replacing bonus actions with actions, you get a move and two actions, done. Bonus actions are great and all but not always clear and my players have to look up if they have a bonus action. Just going with two actions instead of Action, Move and maybe bonus action greatly simplifies things while allowing for those bonus actions to remain.
I'm pretty satisfied with 5e overall though so unless it is either amazing or worth the change without invalidating everything, more akin to 1e-2e changes than 3e-3.5 or 4e and then to 5e, all being from the ground up reinventions and thus new games, I am not really interested and more than likely buying two more 5e PHB and another DMG and MM instead. I'm 46 and learning a new game is just not on my radar with DCC doing a lot of the things I like and 1e really being my favorite version.
