Firstly, since the new Court Wizard changes adding the tornado, i’ve twice had (as a knight) happen when i tried to cold steel a target, the target is switched to a bd and then you commit suicide. The idea behind the knight as a class is that you can keep targets safe and, in case of need, gamble with your life on suspected players. It is very unsatisfactory to then die because a fellow BD member swapped targets on you. Moreover, if you logged who you targeted with your attack, other players will think that your original target is a confirmed BD unless the Court Wizard outs himself at that point, setting BD back even further.
What I would propose is that knight is immune to the retargeting of the Court Wizard, so BD doesn’t get disadvantaged so badly if this scenario occurs and will improve knight gameplay somewhat. Other redirects should still do their job of course, because those are not from the BD faction.
Second suggestion for knight gameplay is that when a knight stands guard, you get a message notifying you (or making a general message with someone send a guard perhaps when king, merc or knight does so, but those guards work differently, so maybe not). As the game is now, knight is often chosen by cult/unseen and neutral killers and it’s just very hard to claim knight if you actually are one. Same as it was with alch some time ago.
