I played Halo since CE, so I faced both Hornet and Wasp on their launch dates. But playing the Wasp, I prefer using that over the others for few reasons.
I am self-dependent, I don’t have to worry about picking people up or facing guns to rely on my shooter. The wasp also has a thinner vehicle design than the hornet. So it can support tighter spaces in fights and angle yourself better within tunnels.
The point of the Wasp is to play as a ground-support police unit from the air. It isn’t a dogfight air unit. Stop flying high in the sky expecting nobody to shoot you down. Stay close to the ground between cover, and be annoying. Hornet and falcon can do it too, I just see the Wasp do it better.
