Is UUV usage by the player an exploit?

[MarkShot]

I recently just started (learned to) use the UUV {mainly in SCXIIC}. My results have improved tremendously. I am able shoot much sooner, accurately wire guide my weapon at most critical moments, and avoid enemy counter-fire if it should come to that.

Given the big impact that employing UUVs makes would you consider this to be a player exploit? {Do some refrain from as a matter of "house rules"?}

Thanks.
