Too late for that I finished 90% of the side content, as for where I'm at, I just finished the warden (into the abyss) quest and have 2 more main quest to finish (the one with Morrigan and probably the last one). I don't even know if I will be able to make my self kill all 10 dragons.
I'd just slam into the main quest. Dragon fights aren't particularity noteworthy and the boss is ridiculously easy.
