There is a possible exploit in the game rules. A team can use only the worst units at their first match, loose and go to the looser line. There, winning games by using 1 shitty config the first time and two good configs then and so, it will save most of good mechs and other stuff for the final, where it can just win the winner round team by using better configs. This is a possible exploit.
Or that "325 tons flat" meant you can't go 320 or 270 tonnes?
Also, a team can have 2 BAs + APC (with a driver-BA) or 1 BA + APC (with a driver-BA)?
