I like to take Blenderfish on Dunes, just because.
Anyways, I agree. People get so used to the 'meta' that they never try the 'weak' builds. Mostly because they don't want to learn how to fly. They just want to drive in a big flying gun and pull the trigger.
That is why I have actually started flying a Pyra after two years of playing. It finally seems like a challenge.
