Class system, Specialists, why not both?

I really think one of the best things we can do for the game is extremely obvious and right in front of noses. A lot of people hate the specialist system but theres also plenty of people that like it. Personally I don't mind specialists but I think the removal of class system has made battlefield hard to balance and in some ways broken. One of the biggest issues is the fact that we have sniper medics anyone running around with other classes gadgets. This has not been ok for the game as an example we have snipers running AA missiles. They tend to sit in weird positions far away from objectives at times which means nowhere is safe as a heli or jet. Also the shear amount of AA missiles running around is NOT ok. We use to have it limited to engineers which were 1/4th the players and engineers had to pick between AA and rocket which cut it down by half again. This made the number of AA running around balanced. Now this fine balance is gone and helis and jets are kind of a joke in the game honestly.

THE SOLUTION
Specialists in this game are already unofficially sorted into groups kind of like classes. When not just make it official? Maker certain specialists medics like Angel, Maria falk. Theres supports like borris fraggers/engineers like sundance and mackay. Limit the gadgets to their class and Problem is solved we can incorporate class system into the new specialists and I feel like everyone would be happy. Some specialists can have one extra gadget from a different class if you don't wanna go all the way but any of these options would in my opinion be 10x better than what we have now.
