1. the cloak
make its as powerful as you want - for singleplayer. In multiplayer it only adds a big amount of randomness an delay (resulting in teleport-like-movement). Make it impossible to shoot shortly after deactivating cloak and make it more visible. For me being invisible should never be possible, only make it easier to pass dangerous places and escape easier.
2. the laser
mastering the recoil of automatic weapons is crucial an fps games, especially on small cq maps. Crysis 2 is full of pretty powerfull assault rifles (with already almost no recoil tap firing), so why taking away the only skill to master with these weapons? Not to talk about the faster strafing bugs...
I know that you will not remove the laser but plz keep in mind that sth like this should be bound to extreme disadvantages such as a highly reduced amount of ammo or a decrease in the fiire rate.
if you will reward aiming and good movement in this game and you will be one step ahead of shooters like bf3 and cod.
Thank you
