1. Well - though by the honor code, that would be considered a LRP action and make said runner dishonorable - typically dumber actions like that are performed by well - newer players. So I'd rather give it the benefit of the doubt and let it go the first time, especially if its clearly a newer player. If it doesn't do anything more, then nothing will come of it. If it continues on with actions alike that - well, it'll be dispatched properly. Though it is dishonorable - it is still a runner, so might as give it a proper fight, instead o' using the funky weapons for dishonorables.
2. Well - non-Yautja can't exactly challenge Yautja to a, honor duel. And considering the circumstances - it'd be wise not to engage anywho, since well - the Queen + Carrier combo would almost assuredly use that as a opportunity to tryna get a predalien. If the Ravager stays groundside after the Queen and the hive has left on the DS, I'd be willing to give it a proper fight, but otherwise - I'd rather not risk the entire hive swarming upon me to infect me + delaying the round because of it, which to some, is quite annoying.
3. As it isn't exactly metaing the honor code in clear terms, only able to be assumed as such, I couldn't safely call the Marine dishonorable - so I would simply, not. I'd still consider the Marine worthy, punch it if it isn't exactly, fighting back, and give it a moment to start fighting back - then go on with the hunt, but as it clearly isn't willing to fight back properly, it would be wise to give it a few chances to escape back to Marine lines safely - as if it doesn't want to fight, it simply doesn't - nothing enjoyable for either side, if you are forcing it to fight.
