Who agrees the precision shooting could use a tweak. Split Gate Arena is the biggest comparison and if Halo had the same or better smoothness in aiming and precision shooting mechanics it would be perfect.
Hopefully they focus on a smooth game experience for everyone. Shooting mechanics to be more precise and not feel like a poorly ported game.
This game has ALOT of Potential to take the causal and competitive shooting market but listening to the community about the fundamentals will be key 
.
Precise shooting, rewarding frag feel with great sound and foot step audio balance is the main concerns from gamers.
Once the game feels smooth and precise, then adding all the extra features will be a plus but most games just keep expanding without keeping core to the fundamentals which most gamers have the biggest pros and cons when discussing a FPS game.
Hopefully they nail this one perfect before release, so the gameplay is enjoyable and then just add lots of features, weapons and maps while updating and listening to the communities biggest complaints.
Fingers Crossed Halo Infinite will get this one just right cause we are all tired of gamers, steamers all making complaints about the same common issues yet nothing is done except adding more features.
Lets hope this is different so we can keep all experienced FPS gamers to stick with a game we can all enjoy.
