Oh I agree.
Not to mention WoE flues 12-15 for 96+ scrolls and the other ones are obtainable from earlier fluxes. I'm not sure about fluxes 1-7, but I know 8-11 dropped 90-95 scrolls.
If Meteor/Arise had similar "obtainment", there'd be scrolls on the AH already, even if there's been no sales. There wasn't a ton of level 96-99 magic, but I know it was obtainable from Jeuno T4-T6 (and now WoE fluxes 12-15). tl;dr's:
- They don't drop from CoP/ToAU VW. If they do, it's highly unlikely.
- They don't drop from Jeuno T6s.
- They DEFINITELY don't drop from Zilart T3's (Hi level 95 content).
- They most likely do NOT drop in WoE.
The likely options, as I said, are Legion (Hall of Mul, would fit their "extremely difficult to obtain" theme I guess) or Provenance.
