Right, because MWLL needs more Shivas in the skies.
Learn to shoot them down Virt.
About 1/3 of my kills usually come from ASF & VTOLs (they're a nice little money earner if you take pot-shots when you see them) and flying things account for at most about 1/5 of my deaths. Sure I engage 3-4 ASF for every 1 ASF I Kill (unless the pilots doing something stupid or is new), but usually they have to RTB after being engaged and most often 2-3 of them will be destroyed due to allied fire from those 4 engagements. When I do get fragged by ASF it was because I was engaging ground targets and the pilot had seen the opportunity and gone for it, or when 2 or 3 ASF are working together well for revenge....that's fair play in my book. I'm not the best AA gunner I know, and 10s feels like an eternity when you're 35kph, but I do it because it earns you cash and rank fast and dependably, while helping the team.
Shivas give you the most money from inflicting damage on them, they're very easy to hit (slow and big) and a lot easier to kill than a Sulla (frankly: the Sullas a PITA for the AA gunner), or even a well piloted VTOL. From my PoV I'd like my skies full of Shivas rather than Sullas

The thing about both the Beatsticks (flying and walking) is not so much the price but the weapon recycle rate. The LB10X&20X firing once every 6s or so (compressing all the firepower of 6s of AC20 fire into that one hit-scan moment!). I do hope eventually that the Devs will realise that the LB-20X completely breaks air-ground gameplay...why would I ever use AC20s on an ASF (something common in ground attack CBT ASF) when thanks to the rate of LB20X fire I will be insta-gibbed if I try to use them (so we get ballooning instead of strafing and never see the heavier AC ASF other than the Beatstick
From the AA gunners PoV the LB-instagib is just as cheesy, when you have to deal with lag and lead and time-on-target to do 60% damage to a Shiva only to have it insta-gib'd by a SCat B is like a slap in the face (that's 1LB20X=4UAC2 and 2UAC5! and happens every day of the week), the 5X is working beautifully with it's new faster RoF, the 10X and in particular the 20X need this attention also!
