(Bear with me, I'll try to whip the question into something answerable by SE standards)
Related to this question, my buddies and I are trying to get some EL going—one challenge from previous 4X is that lack of balance usually meant lack of replay-ability for us (so, people who get stuck with weaker factions don't have much incentive to play). So:
Do all factions have at least one viable win condition?
From what I've read, Diplomatic Victory is almost impossible, but maybe Drakken can still win through other means by imposing peace/alliances on other players and developing their kingdom.
If so, please elaborate on those (i.e., Vaulters: Conquest/Supremacy/Elimination victories, thank to strategic resource production/boosts, that allow bigger/better armies, all other things being equal; Ardent Mages, due to Pillars/Incantations).
