I do like to run the "Arcane Sacrifice" trait on my Gaunt Summoner, especially as the unbinding range was raised to 30". The +9" to his casting range and the re-roll is very powerful. In addition, you can get some Blue Points in the first phase and even increase the number of Pinks above 10 (from the Icon) with the forced battleshock test. With that in mind you won't need the Balewindvortex and can drop the Magister to include an Ogroid wich might cancel enemy shooting from units with more than 1 wound, as long as the Brimstones survive the combat phase.

I guess the same bad wording will apply to the FSWB, as they might have forgotten that units from some battalions have an allegiance that opposes the battalion warscroll. It's hard to think, that they lose their keyword and allegiance just by having a battalion. Well for now it works like this, but then again, which allied battalion (including all units) is cheap enough to be used in any army?
