It's not that impossible if the enemies - the so called low skilled kids (clanmates with other names) - do things to help you getting many xp.
Rasen aka .wha+?Tox!c!ty~ is admin on this server as I mentioned before.

I just played with them on that server before on >railgun<, Rasen played as engineer and he was destroying/repairing/mine-spotting all the time. Of course he did many kills too. (Easy when some of them don't really shoot back).

That's not the way the game should be played, but ... it's their server.
