Hey, posting in this forum for the first time for a while, but this is really absurd.
Demoknights with a proper loadout have 20k HP and hit very hard (very far away too with the Highlander sword) so they're one of the best picks along with Direct Hit Soldier, or Tomislav Heavy.
My experience with this person, "Gobble Blag Blug", is that he was very upset that I started dominating him, so he started claiming I wasn't taking any damage, or that his tomislav shots did "3 or 4" damage to me - when they were actually doing 2000 (?) each. Still, because the Demoknight loadout has such a high health pool, he couldn't kill me and I did.
That's basically the extent of this argument.
Then he switched to Demoknight too, did kill me a few times (unlike what he claims, I wasn't magically "immune" to a charge or anything else), and got dominated again.
There is not much else to say, apart from the fact that he kept going in chat with claims such as "godmode toggling on and off" when I don't think I even have access to that command.
The other "proof" of "Fundamently started dominating the entire server alone" is about the same level. At peak demoknight strength, I was at something like 20 heads today, when I've easily reached 50 or 60 before. This isn't unnatural, the top loadouts in x1000 are just consistently stronger than anything else. Many players can get 5 or 6 dominations on the enemy team, just because some classes have natural advantages.
Edit - on his screenshot, I am indeed wrong, there is no such bullet resistance on demoknights. I checked a few seconds after his screenshot and did tell him I was wrong, but curiously, he didn't include that in his report.
