Looking at Warclans, I won't even rely on getting endless spells and terrain. They will, probably, give us lots of new artefacts, spells WT, and most will be useless because we'll want new battle traits from constellations, which go with a tax of mandatory trait and relic. I really wish that summoning won't be tied to Slann General. Actually, I'd trade massive summoning for better stats on units. After Std Battletome release, there won't be a single faction left fight with which wouldn't be an uphill battle for us.
And I really wish, that battletome is not written by the same people, who designed our magic for GHB.
