Well I'm pretty new to the SP beta but I haven't seen it mentioned before. I was joining the Sarranid's siege on Jeribe castle, with us having over 1000 to the Rhodocks 110, and noticed that the majority of our forces stayed near the bottom part of the siege tower the whole time. Once every so often, a single soldier would make the ascent only to be butchered and this would repeat over again. I tried calling all of them back to follow me, then re-charge, thinking maybe one or 2 soldiers were holding them up, but the same thing continued.
