So I created a new KDF toon and decided to skip the tutorial. When I reported to the prison warden, he gave me... Plasma weapons. A split beam pistol and a high density beam rifle, to be exact. I'm assuming this is a bug, since during the tutorial, if memory serves me right, you are given disruptor weapons; i.e, a compression pistol and a pulsewave assault.
Sounds like it was copypasta'ed from the Romulan tutorial, as those are Romulan weapons.
Yeah, both were done for LoR, so this is probably the explanation. As with other "minor", yet annoying, KDF-related bugs I've posted on the forums in the past months and weeks (e.g., disruptor-pistol clipping error, BoP-wings fold-back error), I fear this will be just another "low priority" issue for the Devs... so don't expect any response :p
