Air vehicle selection, particularly on Reshmaan. I had to hop in fixed-wing to support a push on the north-west airfield, and the choices were between the CAP and CAS Harriers and the RHS A-10A (I believe). Frankly speaking, they all suck pretty hard, and left me struggling to actually be effective at all...
1. The A-10's main cannon aimpoint is about 10 degrees high-left of the aimpoint, and seems to be barely affected by aircraft velocity. I was having to guess where to aim each time, and even when I did manage to get effective strikes (on my 2nd or 3rd burst), the damage was vastly underwhelming - if Aeo can kill a BTR with a .50 in 5 shots, I'd hope to be able to kill it with a burst of 30x 30mm rounds hitting it.
2. The A-10's remaining ground ordnance consists of 4x GBU-12, 2x Maverick (that don't track at all well. It missed a stationary target), and 14x CRV-7 HE rockets. This would be okay, but given the underpowered nature of the cannon and the lack of AT rockets, I was forced to just throw volleys of HE rockets at a BMP in the hopes of getting a lucky disable to stop it rolling over friendlies.
3. The CAS Harrier has 4x GBU and a huge pod of HE rockets. Same issue with not having any really effective anti-armour weaponry apart from the GBU (which vastly restricted my utility due to blast range, and the awkwardness of having to swap in and out of the targeting pod multiples times etc etc).
To be perfectly honest, I'd suggest:
-CAS Harrier be changed from the UK GBU-12 to USMC GBU-12 variant (6 bombs, cannon pod) or USMC AGM-65 variant (4 missiles, cannon pod).
-A-10A be swapped for the vanilla A-10D (usable cannon, 6x AGM-65, 4x GBU-12, 7x CRV-7 HE, 7x CRV-7 AT), or the F-18 (customisable loadouts).
I realise that fixed wing is something that is rarely used properly on the public server, and it's hardly a high priority, but I'd still request that each mission at least have the maker check the variants for usability before pushing their next updates
