Flying encompasses many styles and skills. Tanking has relatively fewer skills, shooting most notably, but trust me, there are guys out there who have honed them to an edge few can aspire to.
BTW, to all fliers who think tanking is "super easy" because of some misleading "2Dv3D" comparison...not necessarily. A fighter was designed to be flown by one person, and most of us have HOTAS setups that allow us to control them in a very natural and integrated manner. The guns are forward firing, maneuvering the airplane and aiming are one.
A tank was designed to be operated a team, but in AHII all team functions must be managed by one player. A tanker, if he is going to maneuver for cover, stop, shoot, maneuver again, must smoothly manage his use of all 3 positions while keeping track of the situation WITHOUT icons.
In one way, the tanking aspect is more like WWII air combat than the flying. No icon, and first sight and first accurate is usually the key to victory.
(For the record, I can't see the %@#%^@% tanks either.)
