I'm going to create a separate topic to discuss this.
I kinda agree and disagree with your point there. I would like to see some kind of realistic aim cap put in for weapons, however I do agree that it should be hard to cap some weapons.
E.g. I should be able to cap a Paineaser relatively easily, however an TL113 AK should be something that if I want to cap aiming on it will require specialization to do it.
I think the point I'm trying to say is that higher TL weapons should be harder to aim/cap aim, as a trade off for their increased damage potential. Would hopefully allow people to trade some damage for a weapon that is easier to aim/cap aiming on, adding possible variety.
I still think aiming on the whole seems messed up since 2.2. It seems very much based on the range of the weapon and not your aiming % on that weapon (assuming the target is in range ofcourse).
