Re: I love PS2 and how it looks, except for one thing.
Did you ever play PS1? The MBT's in PS1 had separated drivers and gunners. you didn't drive + shoot your own tank and you had to get out to swap seats, not hit a button and magically teleport to the other station.
Both of those things are 'borrowed' from BF3, and neither were in PS1. In PS2 you can equip the 'secondary' gun with an AA gun which will make it lethal (atleast somewhat) to aircraft, but again, due to the fact that you can 'hot-swap', you dont 'need' a gunner for that gun. If you get attacked you can simply hot-swap to that weapon.
Im not comparing the damages or ttk of either game such as you are, what im comparing is the actual mechanics they copied.
