Seems like they expect a lot of on the fly switching between gear and ability augments to meet the situation. Unlike SoM where it was pretty much your rune choices and that was it. I wonder if this is sort of their answer to difficulty in the new game, other than the difficulty modes, where if you don't switch up your skill augment choices to exploit weaknesses that everything is just that much harder without it.
They also make it a point to speak about making sure these augments are balanced so there's no best one to roll with.......yeah no. I can already see where there's one augment per ability that you basically want all the time, the others are simply bonus perks. Like, under the "Treasure" ability, your choices are 1) automatically pick up loot 2) get a chance at better loot or 3) increase the speed of domination. (Not sure how that relates to loot but w/e.) Faster domination speed is the obvious, clear winner there. But I suppose if you want to make the game harder on yourself at the very least you have other things to pick as advantages other than the thing that makes it easier to survive fights.
Or as another example the "Elven Light" ability, AKA Wraith Flash. Does fire aoe, frost aoe or poison aoe. Setting aside elemental vulnerabilities, after watching them use the ice aoe I probably wouldn't use it. All that really happens is you freeze everyone in an aoe around for about 4 seconds, which is just about the amount of time it takes you to Flurry a single frozen dude. Compared to fire where everyone takes damage and some run around panicking, or poison where everyone takes damage and is constantly interrupted throwing up everywhere. Of the three, based on what I've seen, the ice augment is the least useful one of the bunch unless you really like having a whole augment that makes it slightly easier to run away from fights. Again, for maximum effectiveness I know which one I'd pick. Each augment may appeal in its own way, but some are clearly more generally and widely useful than others.
At this point I think I'm also a little burnt out on info. Short of story missions it doesn't feel like there's much left to show I think, and I wouldn't want to get more spoilers than I already have about what the story missions are. I can easily see them covering the same stuff for the next ~2 months, methodically making videos about stuff the attentive viewer has already seen, on the lead up to release.
