Since a fair few people seem to be talking about the Valk:squad ratio, here's a fun little thing to try when it goes live.
Have 3 valks with engies as pilots, 6 heavies, gunners optional. No difference so far.
But now, find an area, throw down a mana turret (AI, not AT) with an ammo pack beside it. Get the other two engies to do the same, a hundred or so metres apart, in a nice little line. Then all jump in the valks and go marauding.
The upside? You've got a self-made resupply strip that you don't actually have to land at. Just swoop along the line of mana turrets (that should stand out due to shielding) and get pinged by all three ammo packs in succession, one after another. Spacing will have to be worked out, but you and your friends will all have their heavies nicely stocked, and you'll never have to set foot on the ground again. Ever. Unless you take damage of course.
Mana turret airstrips should look quite pretty at night I think. Perpetual aerial disco is go!
edit: Can you jump from a rumble seat to the pilot's seat? Or is it whoever pulled the Valk is the only possible pilot? I know you can go from pilot to gunner and back, but I'm not sure about rumble seat swaps. Because if you can, swap your engy to gunner, a HA to pilot, then the engy to rumble. Then repair on the fly. It would make having the gunner's seat open an advantage for seat shuffling. Never walk again. Ever.
edit 2: Also, are aerial shotguns any good as an anti-ESF/Valk weapon? Sort of like flak weapons for a Valk, just not. At least you won't miss entirely, and constant hit-pings do a fair bit to drive off air vehicles. A LMG/launcher combo is better, but even as an air-to-ground AI technique, aerial shotgunner might be fun.
