Are you in the TA or the OTC?
If you are in the TA and doing challenging stuff then I'd stay. There are plenty of ways to sell it to OASC. Don't believe all you read on Student Room anyway. They genuinely don't know.
There's lots of other ways of getting in the air that don't involve UAS anyway. Gliding is one of them. Uni/general gliding club would be one. Make sure your CV is peppered with leadership experience in clubs/societies, and with experience of working alongside/leading others from all walks of life. Do some true volunteering.
The RN will be far less fussed about UAS anyway
