I'm not sure what is so bubble-impacted for me. The game has a long history of essentially gear-nerfing current tier fights. That it takes 7 weeks to get a lore weapon without an A6S clear is intentional and means week 7 will see a shift in the A6S experience. This is already a massive difference from 3, since if a group got A1S week 1 and A2S week 2, they had Eso weapons by the time they took 3 on seriously and had no weapon upgrades in the foreseeable future.
Lore weapons will mean only one dash set even with multiple deaths on Blaster (doable now, but tight, should be a nonissue in a couple weeks.) Given that dashes are one of the biggest hurdles in early progression, cutting out the second dash for everyone is huge. Cutting out the third Chakram on Brawler is huge. Increasing the damage done by everyone on Brawler adds is a big deal--compare and contrast early progression A3S adds with later A3S adds and a little damage is a big difference. Increasing the damage done to Midan gunners on Swindler is a big deal. Increased damage means enrage overall becomes less of an issue.
Enumeration and Vortexer are basically the two things least impacted by this, but Enumeration and Elemental Jammer are straight out of the SCoB playbook. People asked for this.
If there's actually an epidemic of people quitting raiding because A6S is too hard and they don't think they can outgear it, okay, but of everyone I know of who's dropped the game lately that's been the case for nobody.
