I don't get this post.
Why do you want to remove the skill based gunplay (recoil which requires proper mouse control), keep the random gunplay (spread), and then not make use of something that's in the game and currently useless?
How does spread have nothing to do with luck? Are you serious? Pick an auto rifle infantry and try to get 100 headshots on a target FROM the bottom of walls flying middle TO the top without letting go of your mouse button. Can you do it?
It doesn't have anything to do with skill. The recoil changes the way the game was played compared to the original and screws the infantry balance. Renegade is a high TTK game, while recoil is a mechanic used to artificially increase the TTK for games where it's already very low (cod/bf). All this change does is make infantry combat a lot slower while indirectly buffing spread/splash weapons and making the game more vehicle focused.
The TTK is high enough that if you can't track and move properly you're not going to be able to kill anything anyway, stacking recoil on top of that is just overkill and pandering to current trends that have no place in this type of game. Same for ADS/slow... these features feel like they were thrown in "just because" and with very little thought put into how they would impact the original gameplay.
(The OP suggestions sound worse than what is ingame now though)
