I’ve been doing the pandaland Raiding with Leashes, so tonight I decided to do a test.
One toon took the portal in Jade Forest. The other toon was a mage and I used multiple hearths to take me to stormwind then used my mage shrine portal from the portal room.
I did all 3 raids and the non-portal toon used the group finder so that she could be teleported to a graveyard vs running out of the raids.
Non-Portal toon: 45:10 min total time
Portal toon: 35:10 minutes total time
