Melee combat is serious business. Please do tell FPS community at large the various ways we can poke,stab,slash,bash and disembowel in your new jewel of the crown . . . RO2:HOS.
Quite honestly, if you can't strangle a Russian conscript to death using the intestines of his still dieing squad leader then it's not a game worth playing!!!
Seriously though, the problem with rank progression is it becomes a bit of a grind. People who don't even enjoy the progression have to do it because you're hindering yourself by not.
And when there's a system in place that means you constantly have to be "the best" it's basically ****ting all over casual gamers who don't have the time to sit in their parents basement power gaming to the top slot. So they then have to deal with johnny hero status having an ingame advantage over them such as lower recoil.
Saying "it's not an advantage worth having really" is kind of an oxymoron. If it's not an advantage worth having then it's not an advantage, is it? And if it is an advantage then everyone will want it because people like being on a level playing field or above that.
Obviously TWI have it under control though, they're not morons they're fully aware of all the issues involved. They've already stated the bulk of hero things are purely aesthetic!
