I don't believe setting up stakes or shields is against the rules in NA1, but actually building siege equipment is (or at least seen as leeching, if that's what he was doing).
Double spawning and doing it again... probably not the best course of action.
Personally I think that both factions need to adapt to the supported mechanics, using the guidelines above. Construction equipment can be very effective when placed properly, not at the edges of the map or out of the way areas (in general). Players who work together as a team will win more consistently than those who do not. Charging recklessly is a valid play style and I will not counsel you to stop doing what you find fun, but if winning is what you find fun, you might consider working with the resources given in the game in the way of controlling cavalry charges and blocking arrow storms and that means cooperating with teammates who must build these fortifications in useful places for the team.
8:39 PM - Klaus: Also, Tydeus never told me to stop building or to stop "leeching" or whatever I was doing wrong. He just kicked me then when I rejoined he said nothing to me, so I had no idea building was a wrong thing to do, then he banned me, I mean Jesus Christ, Tydeus you could tell me what I was doing wrong.
There is no reason to do that. Don't shovel more shit onto the shitfire.
