Thanks for the reply, so just to clarify a few things...
Edit: Oh, and with the T Knife damagelogs, I can't quite remember how that worked so you'd have to test it out for yourself.
- The reason the T knife costs so much is to make it balanced, so yes, you have to decide carefully from the get-go who you want to turn into a T and then acquire enough credits to purchase the item (by killing non-Traitors and not spending credits). So this is a strategy you need to plan out, as opposed to it being a situational item.
- And to fix the 'RDM' problem, I would recommend a pop-up window, similar to that of the random drop, which informs you that you've been turned into a T.
- Cannibalism would have to be single use item, otherwise it would be unbalanced as you've stated, in addition to it making a distinct sound and a fair bit of time to 'devour' the body. The trade off, of course, would be health and removing the body.
