Platform, device and operation system
What were you expecting to happen, and what actually happened
Items of the same rarity have the same number of Attributes
If not at elast items of a higher level could have more if the level is tied to the attribute and not the rarity.
A level 35 Epic Runic Ring (from the rewards)
Versus a level 1 Epic RUnic Ring (from before obviously
And another Level 1 Epic Runic Ring from before
It seems that not all gear was affected equally by the update.
How often does this happen? When did it begin happening?
Most (but not all!!) of my pre 0.36 gear still has 3 attributes. Randomly some of the pre update gear got adjusted.
Steps to make it happen again
Update the game and watch the magic happen.
