I bought a couple light seige engines and some oil yesterday just to have with me on the odd chance they'd come in handy. Later I saw that the T2 swamp keep was being seiged and snuck in through the postern gate and set up an organ gun, it was fun and the Destro players were sort of freaked out when I started dropping fire on the bridge, it took them a long time to figure out wtf was going on and start shooting back. Sadly it was just me and one other guy (who was mostly interested in the renown vendor) 'defending' the thing so it fell pretty quickly.
