Close Quarters was a big POS. I can see the logic in why they did it but it's just too different a style of gameplay when stacked against Vanilla to be enjoyable.
Hopefully AK is better but unless they make some major nerfs to jet strength and buffs to tank armor then the game will be a complete dud. Right now getting in a tank is like signing your own death warrant, AK will only speed up that process.
They also need to increase the effective range of lock on weaponry to jets as well as drastically raise there stall speed. Jets currently can almost hover and kill at will then get away before you can even attain a lock on them, it's ridiculous.
Right now the best defense against a jet is an RPG.
