I'd really like to see the radial leaning replaced wtih correct stance based leaning that does not have the ghetto FP weapon view kanting. As is it's a real eye sore both with respect to realism and in the context of all the other fine features CQB offers in terms of weapon handling, movement, and metrics.
Secondly, realistic assymetrical, mission based game modes; all the tried and true are a good place to start including: VIP Escort
, Escape & Evasion
, and (eye roller) even Demolition
... Though it would be nice to see some more imagnitive realistic mission based play-modes as well..
Lastly, scale body armor as a play option; no professional military or law enforcement Operator (or pro/seasoned Criminal or Terrorist for that matter) is going confornt a lethal scenario, in an urban setting without it. What's more is it has a very positive effect on game-play in making sustained realistic gun fights, and gives the skill curve legs by encouraging Players to aim for smaller soft targets...
