Ackmey your post doesn't make sense. You disagree, then go on to say why it is a good thing.
I personally partially agree with the subject. I think Field op, covertop, and Soldier should be limited.
If there are too many covert ops, it is just a giant sniping battle
Too many soldiers = too many heavies
Too many Field ops = To many guys competing to land an arty or airstrike. Even if the amount of airstrikes is limited, there are still 5 fieldops comping and throwing cans hoping one will actually work. This is fusterating when they do it on a stupid location and waste the airstrike.
My suggestions (per team)
Jaymod:
3 Soldiers (or one of each weapon)
3 Fieldops
4 Covert ops
2 Rifle Nade
ETPub:
1 or 2 Soldiers
2 Fieldops
3 Covert ops
1 Rifle Nade
If you think about a full server, 22 on a team. Having 4 of 22 people covert ops is a lot. It is only really a limit that prevents an overflow, of any of these classes. This means 12 of those classes, and 10 medics/engineers with smg. Not a terrible ratio for the non-medics/engineers.
