I don't mean to start a flame war but the 63e is very different from other regiments, Karth is to say the least, "different" with his ranks. He doesn't really have any core officers, he only has NCO's. Hence why we had a corporal there, we have no North American Sgt, or officer besides Karth. Not to mention a battle as big as one against the 29th isn't something you just let a corporal lead. I don't doubt Offizer or Garma(our cpl's) but it's a big battle and something you let the colonel do. Putting this into context with other regiments, if for example, Grimsight, Armystrong, Tico, Mack, Pepper, Meneloas, Walko, or any other leaders of large, prestigious regiments had a big 1v1 that would be a source or prestige and talk would they let someone else lead? If I were in their shoes I wouldn't, if I lost I would at least want to know that it's my fault, not someone else's so I wouldn't take out my frustrations on someone.
If you were in the middle of an LB and a huge thing happened IRL, for example, something happening to a family member or having a job interview, would you play the game or go to see the family member or do the interview? This is what Karth had to do so you should at least consider that he was out and we could reschedule. Not to mention not all regiments can just call up 40 people to fight at any given time.
Excuse any bad English I might have.
