Okay, so instead of going back and forth on Pyra nerfs, lets actually throw Muse's balancing out the window and look at another solution to this problem.
This involves keeping the pyra as the weaker vessel it is now, ups it's mobility slightly, and also gives us the superior charging, ram, game we want. Then on top of it, gives us an Anglean vessel.
Now awhile back Muse posted some new concept images for Anglean ships (If someone can find them, that would be great). Not the classic Chaladonesc style vessels they did years ago, but updated designs. Ships which look very advanced in tech, don't even remember seeing them have a visible balloon. Could have it similar to the Mobula where it is a bottom mounted, just not as big.
So heres the idea, new ship. Flying wedge/axe. Ship is built for ramming. A giant axe head or pike looking front. Split down the middle, just a huge section of reinforced hull. Guns are separated on both sides but at angles so they can't neutrally face forwards. You'd have to turn the axis all the way to the side to get them forwards.
Perhaps avoid making this OP by having the gun placements in a non symmetrical fashion. So say have one more forward while the other more back. Pilot station ideally would be far back overlooking the vessel.
Engines would be triple engine similar to Pyra. Similar placement. Balloon placement, if under, would be on a ramp that would go under the ship. Hull placement, possibly more topside or vertical placement on the reinforced metal wedge structure.
Flying it. Literally this vessel would be the Pyra before the weight nerf many patches ago. Big and heavy, high speed, not much turning. Designed to charge in and smash things. Guns would have more lateral options but could focus front. Just the angles would be awkward because the wedge would be blocking view and axis. You'd have to have a ship dead to rights on a charge before committing both. Slower mounts would also take time to get into position to be able to hit forward targets.
Lorewise with Anglea...well its a giant flying battering ram. I'm sure sky vikings would have a use for that. Perhaps pre military use it could have been an ice cutting airship? They might have use for that. Specially preventing cities from being taken over by glaciers all the time. Maybe there are even variants which would have a drill on the end.
In fact, could change the wedge and make it a drill head on the front. Spinning or not, you'd be fighting with a big flying drill. Some folks might like that idea. Repurposed ice mining ship becomes deadly ramming ship. I dunno, ideas keep flowing!
