I just found this now.
So are you still doing an introductory class Tourney?
Or just your experimental Class Tourney?
BV is before or after including Piloting skills?
Played with McSlayer tonight so, if anyone else is wondering. We have just been rolling in slack 1D4 (intro - experimental), 1D4 if Intro (IS light - assault), or 1D8 (IS light - Clan assault), and then 1D4 (1 - 4 mechs / player).
Mainly this is just to test for bugs in the latest release each night to help out making the upcoming stable the best it can be. At least mech-wise, if the players wanted to do aero, space battles, combined arms, etc we could do that too its nothing formal.
And the Max BV is per unit "with" piloting skills so, more often than not the players who pick lower BV mechs and then put elite pilots in them tend to win the game we have been noticing.
