[Q]

The planetary defence seems really to be a weakness of the Pyrochette. In my game they didn't build until now weapon platforms, mines or defence satellites even on their homeworlds. Therefore they lost several colonies to the counter attack of the Borg. You may consider to move the building instruction for the defence units more to the top of the list.
But otherwise they do well.
They increased now the number of attack ships to a reasonable amount and grouped them to a efficient fleet.
I enjoy this race an thank you for your work.
