My husband and I have decided to start fresh and grind some new toons to 80 together. I am looking for opinions on what is the best combo for duoing T8 instances once we get pretty well-geared.
well.. t8 instances are pretty solid, you should be able to duo CoA quite easily, the factor with that will be time because theres quite some trash in it. as for the others... i wouldnt suggest duoing them. but to be a little more helpful: probably the best combination in terms of duoing is bruiser+fury (you could also take a warden, but youll be lacking dps then)
I have cleared Chelsith with both Inquisitor/Coercer and Inquisitor/Wizard before so both those combo's work, although other healers may make the duo better.
it would take far too long and some fights would be near impossible to duo due to power drains. i'm sure doable but you will need to keep some mobs in mind like the final in CoA, second and final in vaults, sandstorm, etc etc etc. some of those named i just don't see being all too easy to duo anytime soon.
