Also wenn ich das kurz Zusammenfasse dann sagt er das man die zwar 18 Tier-Stufen im Spiel hat, diese aber vor allem visuell von anderen Gegenständen unterschieden werden. Natürlich ändern sich auch die Werte, aber ein Tier 18 Gegenstand muss nicht besser sein als ein Tier 17 Gegenstand. Es kommt halt immer darauf an ob man die Boni brauchen kann oder nicht. Und dann kommen noch die Gegenstände in Inferno. So gibt es z.B. für jeden Akt in Inferno unterschiedliche Gegenstände, die aber wohl nicht alle als eigene Tier Stufe zu sehen sind, da sich nur die Werte ändern.
There's a confusion of terms making this an issue, but it's really not one.
We separate out 'item tiers' for their visual appearance first and foremost. We have a number of "armor sets" (18?) in the game that match visually, and so we call them 'tiers' because there's no real better way to say it. When all of your items are from that 'tier', you'll match. That doesn't directly determine their stats, though.
They're spread out in a logical progression, and items get more awesome looking as you go further in the game. Ipso facto the higher the visual tier the better chance it's a more powerful item, but it doesn't preclude the possibility of it being worse. You can absolutely find an item from a visual tier back in Hell difficulty that's better than an item using a later visual tier in Inferno.
It's best to just expunge the term 'tier' from your minds, because it really has nothing to do with any kind of stair step or item upgrade approach. It's just models and textures
So yeah, I guess the visual looks are separated out by Act in Inferno. As I said though it doesn't guarantee or preclude an item of a specific 'tier' to be better of worse than another of near proximity.
As I said it's really a non-issue. We need to come up with a better name than 'tier' for the matching art sets, it just makes people think the power is tiered too. Matching art sets!? How about that? Art set? nah....
