Transport Heli earns too little XP after passengers deploy on you

At its current pace, I would estimate it would take flying the heli casually, at least 4-6 months to reach Tier 50 of its respective badge. This is insane and I'm talking about flying it exclusively every match.

Not to mention the insane difficulty it takes to actually stay in the skies longer than 2 minutes. I'm not asking for AA stuff to be nerfed, I'm saying the Transport Heli needs more HP and less firepower if it's going to take THIS LONG to gain XP on the aircraft. Other issues like the buggy HQ AA compound on this problem since there isn't really a safe space for the transport Heli and you're basically just food in the sky, including IN YOUR OWN HQ.

The critical damage penalty which is another compounding hurdle doesn't correlate with the slow XP gain. It's good that critical damage is a thing.

I know that deploying passengers to objectives also yields XP but this is clearly insufficient. There needs to be a XP multiplier for how far away you are from the HQ when passengers spawn on you.
