Examine the video. Here is the most unbiased explanation I can offer.
At 1:44 we see the team lists. A total of 7 people have not spawned on LLJK. It looks like only 1 has not spawned on ATS. LLJK has approximately 20-30 more seconds for those last 7 people to spawn before the ATS infantry engages them.
Carefully watching and pausing every second from the time LLJK is more or less visible after 2:00, I am able to count 4 people who are naked. Two of them have weapons, one appears to have nothing, and one appears to have only arrows.
At 2:20, Zanthos attacks two people who look like they were supposed to be cavalry, because they appear to be using lances but do not have a horse. At least one is able to play cavalry, since he attempts to get on a courser.
But I do not see any player who spawned with armor but no weapons at any point in the video. The video is not the best quality, but it's clear enough that had a number of people spawned weaponless that I would expect to be able to spot one.
I was present during the battle and did not see in public chat that there were any spawning issues at all for LLJK. It is important to say immediately in public if something appears to be broken. I only recall seeing very few naked people and I do not recall seeing anyone else running around weaponless.
ATS did have at least one player spawn without a weapon, but that was a mistake on our side, not a problem with cRPG.
Spectators did clog up the server at the very beginning, an issue not visible in the YouTube video of the battle that affected both teams, and this is something that should be addressed by chadz.
This was DFC's fight, there were only a handful of LLJK hired. Nice tunnel vision though.
