YIt's kinda vague; there is a vocal crowd rabbling about professions being bad but no ones really explaining why or what they prefer.
I'll have a simple example. I have a weaponsmith alt (played as a complete casual alt).
In MoP, he started out making himself a set of green qual armor (with the exception of bracers, who went straight blue qual). Once he had that, he remade pieces of armor until he had blue quality armor, then dps stat (because two pieces had tanking stats, and I was playing as a dps). That occured as he got some ore to play with. When he was done with the processus, he had a full set of blue armor which he kept until 90. He would probably have replaced it in the last zone, but that didn't happen as he was 100 before (all that rest xp). And he was almost maxed in skill. And never made a piece of epic raid-ilvl armor ever.
In WoD? First off, he can't make a full set of anything on his own rythm. There are THREE pieces of "leveling" armor, which have a lower ilvl, and require 92, 95 and 98 level and give him absolutely no skill points whatsoever. And BOP so they can't fuel the enchanter. And yes, he can't make the helm until he is 98... but if he has 100 Truesteel, he can make a helm with a higher ilvl and only 91 level req and gives skill points.
Anyway, that's three pieces. And the guy is 603 in skill now by making the 15 truesteel needed. Only 97 pts to go. Which is going to require logging in DAILY, for around 70 days (because it's yellow, and sometimes, yes, you don't get skill pt for your daily cooldowns) to max.
For the last 3 pieces of crafted armor, HE HAS to make an epic piece. With require 9 days of cooldowns (including building work orders) because Blizzard want the raiders (which he isn't) to have to wait to make those pieces. So, he is not going to go thru the expansion wearing HIS armor, he's going to go thru the expansion wearing his quest greens, like everybody else. Because professions now have exactly ONE purpose: make some LFR filler, PERIOD. There's nothing else remaining in the gutted corpse of professions for the people who liked professions as a gearing for casual play thru the expansion.
The design intention is very clearly a TIME-gated ilvl progression route separate from raiding or apexis.
Yep. Casual? Don't bother with professions, they're no longer for you.
