Only because the ship still gets flown doesn't mean the nerf was fine. Muse basically wanted to get people to not fly the Pyramidion, apparantly their mission failed.
We all know you think the pyramidion is 'weak' at the level you play at. But for the majority of the community this nerf seems perfectly justified.
I could argue that quite a number of players is probably not even aware of this nerf. Not everybody likes this game as we do and shows enough dedication to keep track of patch notes.
Daniel is right, after patch
Random ally pilot: "Okay I'm taking Pyra, I'll charge and tank the enemy and you can hit them from range, be careful though, Spire is squishy!"
Me: "Oh you didn't see the patch notes for 1.4.0?"
Ally Pilot: "Er, what are they then?"
Pyramidion was the single most used ship by very many people and only a small minority check forums or patch notes.. So it is still the most used for a variety of reasons.
Though I admit it is not totally useless and can still put up a fight with the right build, the right build is no longer a charging meta.
