I've been running around Thedas terrorizing everyone with my all mage party. I thought we would be clobbered without a warrior or rogue, but damn, we took on three Pride demons at a rift and came out almost unscathed. I think I used one health potion in that fight. We all have barrier...and are level 17 so that probably helps.
I took them all for the banter, and it's hilarious. I got Solas growling at Dorian, and Dorian trying to be nice but failing miserably; Vivienne trying to be all holier than thou, but Solas and Dorian team up and kick her off her golden pedestal. I mean, if sass was lethal, my party wouldn't make it past Skyhold's gates. The only time they get along is if they're killing something.
It's like, "snarl, snarl, rawr" - DEMON, KILL IT - "snarl, snarl, rawr."
My poor inquisitor is shaking his head going: "Can't we all just get along?"
