Not sure, but crafting the 133 Face brought me from 147 to 148. Though I believe you can get 148 without it (I didn't have Herald of Black Legs or Waist yet at the time).
Ah that's good to know, but I remember reading a few days ago that the crafted face won't change your CR (I think it was Derio that said it) and it totally did for me.
It depends on what gear you have already it's still a 133 piece. I think what he meant or you misunderstood is that it won't take you past 148 CR
Yeah the Neck will be 1200 because it's a drop. R&D should be more open and less expensive, but it won't happen unless the devs can be convinced that R&D gear should be the way to achieve the best gear.
The Shoulders are a drop as well, but they are less expensive. It's very odd. When have Shoulders ever been less expensive than neck pieces in this game ? Not to mention the strange Mark pricing from Ep 19. Hands for 42 instead of 45. Shoulders for 47 instead of 50, etc. It's just all been weird lately.
The shouldera are cheaper because it's in a lesser episode. The higher episode the drops are in, the more scraps they cost
Mark costs were reduced slightly on some items so that the number of marks needed each month is the same.
It's probably because Shoulders from 18-20 onwards drop in the second episode of the cycle, resulting in the cheaper cost of 1000 for the first incarnation of R&D gear for 15-17.
The good news to all of this, you can buy all Episode 20 items from the vendor and still reach maximum CR provided you have everything from Episodes 18-19.
