Exploring Act 6
After putting off act 6 for a long while I have just started it and will become Cav after one more quest, my progress has been very slow as I have been exploring every level of act 6 as a habit since I fully explored every act before this, though it's been quite a pain and a drain on resources.
Should I use resources to explore act 6 as I go along or just complete it and come back to exploration after gathering higher rank champions and counters to Act 6's struggles?
