When I say "level", I mean the minimum player level required to equip the item, not the rating.
Thats what I am slowly figuring out: When I look at the RATING of an item, it list its stats as 1 way - yet when you look at an item from its item level, it list it another. The TIER of the item is more based on the master component level than the individual parts, it seems.
I guess once I have dug into it deeper, I think what I should more accuratelly ask would be:
What are the RATING Tier Breakpoints for individual items? At what RATING is an item considered Tier 1/Tier 2/Tier 3?
When you select your crafting que (Armstech in my case) - you can filter them by RATING - where are the break points?
