I never said adding new planes is a bad thing. What I said was the time taken to create new planes probably could be better spent in developing a more involved/unique/interesting mission system.
I'm just hoping that it doesn't turn into a game like WB where the planes change but the mission system stays the same. Something that gets me into the game and kind of makes me want to stay. i.e. give me:
(if I succeed)
--------------
- glory.. look at that plane burn!
- a feeling of accomplishment, not the "oh look the guy I just shot down is taking off for the 10th time within 60 secs... ugh!"
- rewards.. yes I am the colonel and yes I want to launch a 20 plane strike against field # !
(if I fail)
-----------
- shame.. look at my plane burn

- a feeling that I want to accomplish something, not the "hehehe I'll really piss off those guys attacking the field.. see how fast I can takeoff when being immediately shot down.. uhm shouldn't I be penalized? at least have to takeoff from another field ?"
- sigh.. I wish I could plan a mission that the automated mission generator would assign to people, field # sure looks ready to attack who is our stupid general anyways?!
