I can imagine the combo of R1 and the right stick feeling odd if it's done without a reason, but right stick is definitely the default for radial menus. I even googled itdefinetly not for rachet and clank. to bring up the weapon wheel you hold down triangle and select with the left analog. it wouldn't even be possible to controll the weapon wheel with a right analog and continue to press triangle outside of a "claw grip". the point is the control is split left/right. if the radial menu is access via the d-pad (which is common enough) i would expect the right analog to be used.
I kinda view getting a plat as rewarding a game, if that makes sense. I'd purposefully avoid getting the plat if I wasn't liking it a lot. I'm not a trophy hunter though. Only have plats for Uncharted 2, Uncharted Golden Abyss, Uncharted 4, God of War, telltale forced plat, and Astro's Playroom.
it felt terrible having it be R1 and R. this is not standard.
