-increase the amount of bullets you can take in armor mode.
-increase the distance at where you can spot cloaked/uncloaked enemies with nano vision ( slightly less than the demo ) and make it use twice as much suit energy.
-overhaul the shooting mecanics
*remove hitscan and instead replace it with bulletphysics so you actually feel like your hitting your target
( also this puts people with aweful connection, for ex. laggswitchers, in a disadvantage ).
this also wont cause instant death.
( not like BFBC2 tho, because in that game the bullets go kinda to slow. )
*simplify and correct the hit detection
( example : legs 6 shots/ arms 7 shots/ balls, throat, neck and head 2 shots/ torso 4-5 shots... snipers should be doing about twice more damage. )
and make every bullet count and register every bullet/hit. sometimes bullet seem to have absolutly no effect on the enemy.
-make the suit energy pool about 40% larger but remove the regeneration.
Each dogtag should recharge around 5-15% depending on how fast you pick it up after you kill your target.
( this will massivly reduce the overuse of stealth. and add alot more tactical gameplay. )
-and finally make a perk which should recharge the nanosuit energy over time ( like 1% per second )
...
this should make the multiplayer actually fun.
