Not speaking as APAT "staff", but as this Event is already able to attract MANY Forums with 10 players, I don"t think we"ll need to go down the route of changing anything.
The mooted idea was to consider reducing the team members to enable more teams to be represented not as a slight on the numbers of players wanting to play, as there seems to be a huge amount of interest and so many teams will miss out, whether APAT select the 16 teams or they are drawn at random.
If the venue can only accomodate 160 players why not consider reducing the players per team to up the number of teams and create a larger team / forum competition?
If this is the APAT Team Championship, surely it is worth considering having as many teams as possible represented?
