Got bored of reading the last 15 pages so here's an idea, sorry if anyone else said it.
For the finals of this league each regiment must post, let's say 30 names. (Subject to change) These 30 players are the only members allowed in the TNWL matches, another regimental group could be made for this like the 63e has their guard group. If another member is spotted he will be taken out of the event and the regiment will be given a heads up, It might also be a good idea to get (or try to get) those 30 players ID's.
This would call for a lot of discipline from the refs and regimental players, but I think we could do it :p
