The effects on siege servers mean that catapaults need to be either re-worked or cut out altogether. In the first place, the damage they do currently carries over from round to round, meaning that after the first bombardment all subsequent rounds are more or less automatic victories for the attacking team which simply has to charge through the gap. Secondly the lowering of sections often causes bugs, with characters sinking into floors and getting stuck in eternal falling loops, or spawning in sections where the exit has sunk underground, leaving the character stuck permanently at spawn. If catapaults are to work I suggest that they simply do a great deal of damage over a wide area, limiting them to killing defenders on walls and breaking gates and doors. As they are now, they cause too much game breaking weirdness.
