I've brought it up before, but can I make an official petition of either Sam or Chase, or both, to change the way we roll powers for the Oct 13th tournament? I don't know how you did it at the minivitational, but previously Sam ruled you have to pick the tables you'll be rolling on when making your army list.
I get the reasons for that, not tailoring your powers for your opponent, but the rulebook very specifically allows you to pick your powers (whether to switch them out, and what tables to roll on) not only by the game, but after each individual roll, so this is a HUGE departure from RAW.
Moreover, I don't think it's at all necessary. The Divination Discipline aside, I think most of the BRB powers are pretty weak, so tailoring the discipline for the opponent is one of the only things they have going for them. People with access to Divination (like me) are pretty much just going to pick that all the time anyway, so it doesn't really do any harm their, either.
