In my hit gear atm, Heroics completed with the above 5 - UK,DTK minus Novos - too lazy to try, Gundrak,Nexus,CoS,Nax 4 bosses with all above minus healer.
Negatives -
Levelling up is a major pain - having to go to different trainer.
Specs sometimes are not cookie cutters for certain builds - see my lock.
Positives -
No gear is really wasted off bosses.
More characters available for individual play.
