From Miuna's live translation on discord Reddit FFXIV at the moment of that image:
"A lot of greyed out skills..."
"there were too many skills with similar effects, we merged a lot or remade them"
"Byregot's Blessing successrate got bumped to 100% for example"
"We believe there are a lot of players that have leveld and geared their crafters/gatherers, but have no idea on what they are doing "Someone please give me a macro" and that is okay of course, but we simplified it so more people might be able to enjoy and understand crafting/gathering better"
"5.1 will have the first adjustments, there will be more in 5.2"
"We are working on high difficulty crafting recipes as well"
