We should be able to research planes now like the helis. Tank battle RP should also be able to apply for researching planes.
You can already use planes in GRB, it might take forever to grind planes there but are you really in a hurry to experience the premium spam and godawful balancing of higher ranks
Depends. Some players run up big scores playing CAP in GRB.
I am talking about the new option to research helis while playing tanks. All of your tank battle RP goes to helis if you check the box at the bottom of the Army or Helis research screen. It would be nice to have this option for planes also.
