So I finally made the jump over to free aim lobbies online, (because I was getting sick and tired of being one shotted while in a heli or car from several blocks away.)
and I must say:
I've been pleasantly surprised! Not only are people more mature (not as many tanks or random people killing you for no reason.) but It's actually a lot more competitive!
Me and one guy kept going at it for several minutes until finally I challenged to a 1v1 deathmatch which actually turned out to be epic! 6-5 victory with 10 seconds left.
Spawn killing is drasticly decreased because of what I'd like to call "the added realism" of aiming, therefore it's actually easier to escape any spawn camp situation which is also refreshing.
I've had no issues finding full lobbies in free roam and activities. Overall the past few days have been a blast. I'll NEVER go back to auto aim.
The downfall is there is a little bit of a learning curve as it does take a few hours to get use to aiming on your own, but after that It's a piece of cake and I actually find myself killing NPC's (during jobs) much easier as I can automatically aim at the head level as opposed to locking onto the chest and having to swipe up towards the head.
If you haven't tried it and want a much better experience I highly recommend
