There was multiple missions where Kal acted as leader of the Null. However, through combat it was Ordo. However, my argument of practicality for our server and the lore behind my -1 stand. Kal did not act over Covert, Foxtrot or Delta. That's 3/5ths of the Regiment, it would be asinine to just throw a named character that has supporting lore into a position he has no business being. For my practicality argument, why mess with something that has been successful in the server. I strongly encourage you to read lore as well, because in reality Null wouldn't even be together 90% of the time, during that time they were on missions assigned to them by Kal Skirata.
Isolated Incident, just because he worked one mission with Delta doesn't mean it makes sense lore wise for him to be in charge of them. Sev's feelings regarding Kal also doesn't change the fact he wasn't in charge of that squad. Also your last sentence contradicts your point. While Delta were looking for Ko Sai they never found her matter a fact Delta was unaware of what happened with Ko Sai, they were presented with her head by Skirata and was told it was a suicide just to simply to get the Republic off the track of searching for her. They weren't filled in by Kal about anything that happened.
Korm bruh, your a great Kal however, I do find what you're doing to be selfish. If you want to be Regimental Commander you need to accept the fact that Kal is not the Regimental here nor was he in lore. Kal belongs with Null Squad.
