Yes!!
I have been an avid PvPer since launch with a couple gaps in the game as a whole, for real life reasons, but I came back just before 5.7 and the struggle to get gear is obscene. PvPers don't generally have credits, they are busy PvPing (which gives a laughable amount of anything for that matter.) In 3 months of PvPing I have barely gone from new 70s to a couple rare 248s, mostly 242s, and still some 230s (averaging 24-30 hours / week) that is crazy and that is with giving unassembled components from one toon to another and running PvE which I personally don't like because of the monotonous repetition. Of the 6 primary toons I play, 2 have decent gear the rest are stuck in 230 unless they miraculously got lucky with RNG. In the past this difference in available rewards from PvP was offset by PvP armor, easier to obtain and inferior to PvE based armor except in PvP. Now there is this ridiculous gap. I like the idea of not having augments compute in WZs. I'm not usually one to hold on to the old and I'll say I am ignorant to the reason why they got rid of expertise, but from a casual PvPer's perspective, expertise worked.
I also don't have the time to spend looking up the latest bolster work-around. Actually saying it out loud makes me wonder, why have bolster in the first place? Why not just have 1 tier easily acquired and 1 worked on?
