Because that's what happened to my Elemental Mithral Breastplate from TS.
Really? Something that used to be nice little gear for ML 8 is now not usable until level 11?
Devs, can we please get some notification that you're going to **** up our gear before I stick a diamond of vitality in it because I plan on using it every evasion life?
I'm not sure why for some reason, me having a reasonably good piece of armor is suddenly overpowered, but me being able to get a +5 damage item at the same level (which is more powerful than every single piece of gear released in the first 6 years of the game) is not?
Really frustrated. I've spent 5 years on this toon, am a completionist with 20 or so lives, and now you're messing with stuff in my TR cache. I can understand if you want to take away my superior stability items. I was sad, but dealt with it; I am angry that you nerfed crafting invulnerability items. I'm downright furious that you CHANGED THE MINIMUM LEVEL OF A PIECE OF RAID LOOT.
Low. Really low.
