It was just a fun thing to try out. Iirc someone was talking about health regen on another TQ.net thread and I thought it might be fun to see how far it could be pushed. Bear in mind that these builds were looking for HR first and foremost, resistances and anything else are way secondary - and given that TQIT (and I assume AE as well) knocks your resistances down by 75% in Legendary they may very well suck. I haven't looked at them for a while, what with GD testing, but I did put them back into the save file to try out in AE and the expansion so will get around to them some time.
I'm still the same with GD affixes and suffixes. I know some, but still have to look at others to see what they do. As for TQ affixes Exalted is the only one and is always on a green item, suffixes are Recovery, Regeneration, Renewal, Rejuvenation and can be on both yellow and green items.
