Honestly, coming from Pathfinder 1e (where you needed a feat to use combat maneouvers without provoking an AoO) I was a real fan of 5e allowing for more use of those mechanics without paying a feat tax. It's unfortunate that they're rarely worth using in place of dealing damage, but that's a seperate issue. Shoving, Disarming and Grappling are available to everyone in 5e without any feat or class investment, at least.
