Why transport helicopter is not available in Exodus conquest after season 2?

@X-Sunslayer-X breakthrough is totally a mess in 2042; i don't play it at all and I agree that the heli in exposure breakthrough was an unbalanced issue. But i am talking about exodus conquest on maps like Caspian boarder. Instead of a simple nerf they totally removed this heli from the game. Since no one play 128 conquest it means that this heli is totally removed from the game! I honestly like to see the same way of nerf (read it removing!) for Mackay who has ruined all maps with that ridicules grappling hook lol.
