A lot of stuff when out over adding a Sturmtiger and the Super Pershing. Then people started asking to add the Maus.

Just that sheer amount of stupidity and the fact that Xalibur over-controled his own devs (or lack thereof, sometimes) brought the entire rotten structure down.
Also the fact that Xalibur pissed off Ruhrpottpatriot, probably the best-known dev for the BK mod. He put a whole lot of time and sweat into re-working the Terror Doctrine, which was horrendously OP at the time, into a completely new doctrine (the name I can't remember ATM, it was years ago). And Xalibur just sort of flicked it away.

If any of you have been with the Eastern Front mod before the Great Purge there, you'd know what I'm talking about. Except for BK, it just went beyond the point of no return.
