As mentioned here:
The unlimited health potion tinker WAS basically the only usable one this expac, since there’s no “refurbished” brez, and the refurbished invis one hasn’t seen use with almost none of the dungeons having invis skips. Now the new Invigorating Healing Potion heals for 6.4 mil vs 4.6 on the 3 star tinker, -30% burn damage. Can we get this patched up to 7ish million with the burn, so that its usable again?
