I think in Zeta you are undervaluing the returning WL teams. I'm a long time GM of RToF and I think Blazz would agree that #5 is probably a bit high. RToF has the talent, so it's definitely possible though.
In Alpha, Omerta and Dallas can probably be swapped imo. Dallas won its conference in CPL at lvl 67, so 19-1 in Canada isn't exactly too difficult.
Juggs are going to be dangerous this season. They're got some serious gameplanners over there. 8-8 with the youngest, lowest level roster in WL 2 seasons ago. Now they're older and better and back for more.
