A fundamental problem with the Pyra is the weight. It is stupidly heavy for being the second smallest ship in the game. A Galleon should not bounce off a Pyra. This is mainly because of everyone's desire for it to be a ram happy ship 'cause its got a pointy end. A new 'bonus damage for hitting a ship with this part of your ship' must be added to fix this problem. Keep the ram, lose the weight.
A second fundamental problem is that it is too easy to engineer to keep it in top maneuvering from. The solution, sadly, was to reduce the top maneuvering abilities and ability to take much damage. That is the only solution possible adjusting just numbers. My solution to this is not to change the numbers, but to change the ship. Make another catwalk (like the front) over the rear engine. Put two more small engines up there, further out than than the ones below. Attach them directly to the 'ramming' framework instead of the main hull. Combined with the other engines, your ship will be fast, nimble, with pretty fast turning ability. However, they are obviously much harder to maintain. Lose them and you are reduced to the current Pyra. On a burn in, you would be required to keep two engineers on engines (like most other ships). Once in battle, those engines will start to go neglected. This would put it on a more level playing field with the other ships.
Not sure why the hwacha was reduced to 2 degrees instead of 1 with no other changes. I had suggested the nerf to Heavy along with a buff by removing the ammo reduction, a slight damage increase, and a 1 degree reduction in hwacha jitter because people would complain about not having laser missiles anymore. Perhaps I should send another email.
