My understanding is that they are adding thermals and slipstreams which will effectively let you climb using less stamina (this is also how the very long distance fliers irl like vultures and albatross fly with little effort irl). I thought I heard it was on HT already? But I may have been incorrect there.
Regardless, it seems like the devs do hear you, and want to make ptera less painful to move around (I also saw someone say it was getting ground movement adjusted too???).
But at the same time, limiting how long ptera can be in the air when its not using features like thermals is really important. Back on Spiro, it was a pretty common issue that ptera could literally peck stego or carno to death, and they couldn't do much about it because they couldn't outrun, they can't jump, and neither at the time had upward facing attacks. It was not fair to the full grown, full health carnos, ceras, and stegos. I don't personally mind if ptera takes advantage of a heavily injured dino to finish it off, but they should not be able to fly without any limits whatsoever - its unfair to the rest of the roster.
