I remember the good ole' days of battling for the blue dragon in felwood and using the LOS trick on the first boss of MC before they patched it. I came back right before WotLK and I noticed everything was much easier.
Can't really test things like this with a scale model, sure the frame alone stands up but what about all the extra weight of all the insulation walls people their crap etc. I,m guessing it would take around 3.6 secs to fall.
I can't remember the name of the mod but I'm 100% sure the titans etcs were stolen from a bf42 mod that never made it.
Edit: the name was eternal silence and they released it on source.
