The overall goal in AirRB is winning the battle. 3 ways are possible: Winning on tickets, kill all enemy players, and on some maps in lower BRs destroying the AF. These maps are the only battles bombing could be usefull. But only on specific cirumstances: The team have enough bombers with enough loadout to do it in one run. A second run isn’t possible because of time limitation and af aa.
So universal tactics are only 1 and 2. For both scenarios your team need no bombers nor ground attackers except some BRs with very strong ground attackers with airspawn. Same here, you have to do it in the first run.
Above rank VI the only reliable way to win is killing the enemy team. So the team with the most fighting players has the advantage from the beginning.
If you follow this logic every plane other than fighters or capable of fighting properly is a disdadvantage to the team except the two scenarios above.
To all argueing they are only grinding: What you are doing at the end? Own a toptier jet with no clue what to do…
So learn to fight from the beginning. Sure it’s a long way, but grinding to toptier is a long way anyway.
