Confused about gear progression after 3.0 from lvl 50-60?

[Andy22]

Hi,

im confused on how the gear progression works after i hit 50 and while leveling to 60? Im not yet 50 so i just want to-do some general research. The confusing part is the new 3.0 gear/stones/dungeons.

It seems the main goal is to get to ilvl 142, so you can run the lvl60 "law" dungeons via DF?
Only "The Vault" + "The Great Gubal Library" seem to drop such ilvl, without requiring a high ilvl them-self? The other source seem the daily leveling roulette for 100 law stones and finally expansive crafted gear.

My main confusion/concern is this: Except for unlocking the "high Roulette" and fun, whats the point in doing all the "old" lvl 50 dungeons more than once? Even the first lvl51 dungeon has ilvl120 drops.

So basically what ilvl is recommend to start running the 51-59 dungeons as a tank and are there any other sources accessible for a fresh lvl50-60?

thx
Andy
