This player, Joan-of-Arc, was was attempting to damage other players and their horses, repeatedly. Screenshots provided below. Date and time would have been today, November 19th, at approximately 9:30 a.m to 9:50 a.m, on server NW_Official_NA_1. I have no previous relationship with this individual as far as I know, I wrote nothing to them during the game prior to this event, and barely anything during it. In short I can see no reasoning for this attack except some 'anti-dragoon' sentiment expressed by other players (who did not attack and followed the rules as near as I could tell) in an earlier match.
This behavior continued past this initial attack.
Earlier (no screenshot as I presumed it was just an accident) in a previous match this behavior appeared to begin, although I can not, for certain, claim that it was this player who initiated it at that time as I did not choose to figure out who had conducted it.
As this counts for both attacking (repeatedly and intentionally) team mates, and also was horse killing I formally request this player be banned.
