I do not recall ever knocking you down. If I did, I apologize, usually I do it in game when it happens. It was the first round and that is my default set-up. I don't usually spawn with a horse on Heisenwhatever Monastary, but since I had anyways, I thought I'd make the most of it and charge the enemy as they came up the stairs, a tactic that later worked to good effect, might I add.
However, none of this justifies your intentional teamwounding, which is against the rules. Please consider this a warning as I am withdrawing my ban request. I've certainly killed horses in spawn because the owners kept knocking me over... but that was before I knew the rules.
