I don't count having to aim for an extended amount of time "dumb". So many times in the regular modes have I watched kill cam replays & the opponent literally 'pray & spray'ed me--jam on the fire button, then sweep. That's "dumb" to me. HC seems to be a game of 'who can see each other first'. That's fine and all, but it negates all of the other skills. And don't give me the "no HUD/crosshairs" argument, if that's where it would go next. It's not hard to aim in this game, HUD or no HUD.
"R&G" games are fun as hell to me. They keep if fast-paced & you most definitely need skills for them. Those skills might just not be what you are good at and/or take no interest in. Regardless, skills they still are. I also like the fact that everyone starts on an equal level in OSFFA and weapon/perk spawns keep the game a little more dynamic.
