On Tomi
I don't mean player behavior (they are changeable so hard to predict).
I mean unchangeable conditions like:

1. only 1 map for 4vs4 (can be a bit boring and tie breakers ....)
2. no lobby chat - it will absolutely make game harder
3. problems with joining game
a)i'm not sure yet (checking it with clannies) but having english version i suffer problems with joining polish language versions. this bug occured at mtw 2 and i'm afraid its still same problem
b)generally its hard to join game
4. another problem - if someone quit game, there is no quit communication (or i just did not spectate it), only information about result

Of course I'm talking from land perspective but im not sailor. :)
