As people already said locking PVE content behind a 4.5-5 million dollar paywall is no-go. Even while I like PVE content personally, no way I'm spending that much for a couple of missions.
While the Tula had vertical flight capability and buoyancy, this thing is basically a flying target with guns, which are of no use against anything nimble with rockets or a lone ground unit with an explosive sniper rifle. Both cost a sh*tton of cash, require multiple people to operate propery, but at least Tula has these things, while the Bombushka only has guns and limited protection against ordinances. It's a flashy toy that will get boring after a day or two. No utility, no intimidation, all price.
Now if this thing had PVE missions and an ability to launch SR's and possibly other business missions on the go, had a Fulton system to recover operatives with the cargo/supplies, then the price could be somewhat justified. Plus an armor that doesn't suck ass and could make the plane THE MOC OF THE SKIES. 15 ROCKETS TO DESTROY IT, NOW THAT WOULD BE BETTER.
And a VIP mission would be nice too, but ideally, every one of these new planes and choppers should have had one.
