I'm still slowly leveling, doing a mix of questing and instances. Instances are getting a bit easier as I get better at boxing and replace quest gear with instance gear.. And being higher level.. Tank is 74 and others are 72. The tank is leveling quicker due to boa's. 20% extra exp is nice. Only completed uk and nexus so far. It's a bit of a grind but has to be done.

Plan is to get this team to 80 earn some badges for boa's and boost other teams to 60 (before RAF runs out) with the pally or a bear and then just level the other teams up with rested slowly.

Just takes a bit of time

Best approach to leveling seems to be what ever one likes or dislikes less to get the job done
