What can we do to make BF3 better?
Add in smoke grenades (Maybe its a later unlock, idk)
Add in leaning (it will greatly improve this game's playability)
Add in a first person cover system (loved this in RO2)
Add in crouched sprinting (loved this in RO2)
Add in no clip through teammates (nothing like getting stuck behind a soul train or pushed around because teammates are colliding with each other)
Add in repercussions to players shooting RPGs in-doors
Allow sprinting to break out of toggle ironsights (might be a PS3 only issue)
Allow weapon customization through the default class screen instead of going into loadout screen
Allow the ability to skip killcam
Allow the ability to adjust chat box (it resolution is low enough it will disable you from clicking on items in the menu if its overlapping)
Remove windows facing defending team's spawn at the last objective on Operation Metro (just a spawn killing fest)
Tweak flashlight/laser from blinding players when an enemy isn't aiming exactly at their eyes (100% encounters always blinding and I'm sure they aren't all aiming at my head every time)
Tweak flashlight/laser from blinding your own teammates (playability/fun factor > realism || It's even a BF3 Dev motto follow it

)
Tweak flashlight/laser to have reduced effectiveness in broad daylight at ranges.
Tweak font colors (use red instead of blue, why? because mcom screen is blue and so is the message telling you to press a key to arm/disarm it)
Tweak messages so they don't block out your screen at a mcom (I saw reload message, pickup weapon message, and disarm message all at once almost overlapping and all in the same font color)
If RO2 and BF3 made a baby, I'll adopt it as my own.
