Me and Void put together a group last night for Normal NH, grabbed 1 tank, and 2 healers, and another ranged from the group finder. We 1 shot the first 3 bosses, Scorp / Chrono / Trillax.
We tried Spellblade but weren't unsure due to not having appropriate healing. We wiped at 28%, but as far as I could tell it was fine we just didn't have the healing. Tank died - not any of the hunters.
We skipped Spellblade and went to Krosus, there were more people queued in looking to join so we added some DPS to the mix. 1 shot Krosus.
Heading to Tich and everyone just started to leave without saying anything. It was extremely odd and we were baffled. I assume people weren't thrilled with boxing but we were pulling the weight and downing the bosses without issue.
We went Yolo on Tich with no tanks and a Paladin healer with ilvl 855. We got him to 25%. Was insane. Just 10 hunters and 1 Paladin.
If there is no one in melee range he doesn't spawn his Blood adds.

This team is pretty strong and a little more gear and we should be able to overpower a lot of these bosses. We're looking at trying out Heroic EN, and potentially Heroic ToV - unsure though on Odyn for difficulty.

If there was another boxer that was healing/tanking oriented, could do amazing things. Though filling that role would be super tough to deal with the mechanics. Trying to to sell solo players to join in is a bit of an uphill battle.
