still worth it, maybe, but comparing the two difficulties we're talking here. Wayyyy different.
Those augs have been in game for a long time and are no drop.
These augs are dropable, and can be used by multiple classes.
I can agree with you that levels 1 and 2 of the augs are garabge. Level one should be a 150 damage proc, and level 2 should be about 325, then the rest of the tiers are fine. If they were ment to help out lower players like the armor was then the minimal upgrades they provide are not worth it. 500k+ in ore, 300k in Lightstones, and like 70k in essenes really doesnt make me want to farm something for like t1. i believe that 800k (assuming you farmed some mats) is worth the investment for 325 damage (talking about getting the aug at level 2 if it was about 325 damage)
