The power drop is notable.
Origins mages could just faceroll anything, was ridiculous. Mana clash, followed up with whatever you want, Virulant Bomb, Freeze, Nuke, Mind Blast (you're in my personal space, back off), leech health/mp (whatever it was), cup of tea, wait for rest of party to despair at not getting a hit in and returning to rejoin you.
Inquisition mages don't seem that 'boom-tastic', they do set up a lot of things though, Freeze-Shatter, Immolate-Fear and what not but they don't really decimate everything before I have a chance to get my sword out.
If anything, Rogue archers are quite powerful, on top of that, Tanks are... tanks now.
An Origins Dex-Warrior (thanks attribute bugs) was just nuts, nothing would take him down, backed up with a mage? Instant-win.
Inquisition sword and board? He'll take a dragon down on his own. Might take an hour but he'll do it with NO damage at all, - hey thanks shield wall!-, guard, armour, HP and shield wall = jesus christ, why won't you die? It's ridiculous. Though I love it anyway since I sword and board throughout the series.
