Then I wouldn't want to be in the skin of someone who's up against Oathbound mixed with, let's say, Vanguard who rely on ranged weapons. Then I believe this would really be a death sentence, unless I'm missing something here. However I get a feeling, that a single Seer unit with Fatalism combined with a bunch of ranged units, could really mess up at least a key unit in an enemy stack. I wonder how this will workout.With a ranged faction? Deinitely. But given how accuracy usually isn't a problem with melee, it's kinda there (I presume) to cover more ground for those few ranged attacks options, which is to manage to hit in the first place, to make more of their attacks count when there's a smaller window of them getting attacks in since the other units will need to reach melee. Or those occasions where accuracy debuffs are used. It'll be curious how it may play with certain NPC factions or that option to go Seer build.
Just a guess. There's several tools they're given that are insanely good taken out of context, particularly the Seers, but I'm sure to make a very heavy melee faction work you need these to cover a very big weakness and give you the tools to strategically work around them.
