I actually found the new Tomb Raider (e.g. Rise of the Tomb Raider) less copy pasty than the old ones and had really great map design, but i get what you mean if you're referring to the old ones, old Halo games did it too.
I also found the movement to be a little annoying, considering Titanfall mechanics and gameplay were so fluid, the controls and movement in this game sometimes feel too clunky. When you are scaling and jumping things, it definitely feels less fluid and dynamic than the newer Tomb Raiders, at least on PC. And yeah getting cosmetics from chests is kind of pointless, when all you're trying to get are the stims if anything.
