if koth is too soon or you dont get a spot/team to play with then the next NQ newbie tourny will hopefully be in april (i think). its also a great day, relaxed and is only for newbs.
there are some good teams in koth who train with players in higher divisions. so as a starter point it is good only if you have enough experience to give it a good go, if you want absolute newbie comp goto nq they actually go through fields layouts game plans so if you have no idea the firm lads are there to help you out. all depends on how much of a noob you class yourself as
