Steppen not talking about the dragon but how the system in general works. Try crafting without spending sometime googling it, or having played previous games.
To that - I can now do about 60% damage by just controlling blackwall, but the rest of my team dies. Dorian and Solas are ALWAYS the first to go. The ai is good awfully stupid. How do you keep the mages alive in a fight like this? I try micro managing and it works until my timing is off and they get one shoted.
I am taking all these suggestions to heart but how do you micromanage 4 team members all at once? It almost seems better to just go in with just blackwall and my rouge and fight.
For dragon fights, you want to make heavy use of Hold Position. When you get a mage within the wing radius and outside of kicking range, you want to double-click that position until a shield appears on the ground. They'll stay in that spot until they're forced out of it or until you move them to another location.
Otherwise, mages automatically try to be a little farther away, which is great for most fights but will get them wing-vortexed when fighting a dragon.
Save Fade Step for those moments when the dragon leaps backward and winds up for a breath attack. If the dragon spins in place, set new Hold locations for your mages so they're beside or behind the dragon again.
If Blackwall is doing his job, the dragon should mostly be trying to swipe at him, rather than moving all over the map. If you see that the dragon has lost the Taunted condition (shows up in the tooltip in tac cam), make sure Blackwall reapplies it. When the dragon has more threat from the back or sides, she starts moving around more - which means more microing your party's position.
(sidenote: the previous games didn't have crafting, so we're
all learning this as we go
