Since I don't know yet if its going to be fft or random tourney Im gonna state my thoughts on how it should go down on both of these.
Random: foi is very easy to play from random, so that would definetly be a viable option, but also very boring to play a dozen of games on same map :/.
FFT: I agree with most of palla's arguments, exept for not including dunharrow, I for once rly enjoy playing on that map, and if the tourney was to be a fft then I would probably pick mordor. Knowing the imbalances of this map due to host spot having a slightly advantage giving it to the offhost should even things up a little.
Host picks map offhost picks spot is a great rule.
Also im voulunteering as a neutral host, many can confirm I got a flawless host with no lag even with 8 players.
