If a captain in a pyra has mostly wins now days, he is either always against easier opponents, or he is a good tactician with a good crew...
Everything the pyra can do, other ships can do too..
The only two things the Pyra has against other ships is its compact size, making it harder for mid level gunners to hit, and making it easier to be sneaky with... But the squid has a similar size...
And the pyra is easy to maintain, which only benefits lower levels, once crew learn to crew, Junkers, Squids, Mobula and Spires they will not need the Pyra.
