Sorry for your guys bad experiences. We do invite the pubbies to play but we cant let them turn it in to a a pubby free for all. This is new to us and we are slowly figuring out how to incorporate all these different people. For the most part it had been working well. A ship is a major asset that requires a whole squad to operate. if a team lets a lone wolf pubby drive the thing that team is going to lose. That said, if you are in a squad and use VOIP or TS they should let you on the ship. If they kicked you anyway then they overdid it. BTW, you can ask for the TS passwords in game. They don't want them posted publicly because of past spam problems.
I happen to know that the pubby server has rules about "wasting assets", so let's not act all surprised. Next week will include Midway, which has the most naval assets yet. Don't expect to jump into the driver seat of the Battleship and take it where ever you want just because I advertised "pubbies welcome". If you want to use those major assets, join a squad, communicate and follow your SLs orders. If they are being unreasonable then make a complaint and the admin will try to accommodate you.
If this is not good enough for you Born To Be Wild ways, the maps are on 3 server all week. You can pubby your ass off Sunday through Friday, if you get enough buddies to join.
