I think Criterion was a good chance to actually give something like glazes/twines earlier than the 24 mans. The biggest barrier to gearing up even if you're doing savage every week is those upgrade materials. It took me close to 16 weeks of reclears to fully gear 2 jobs. And it wasn't because I was hurting for loot, I got my actual raid drops very early because we did dps priority. It was because glazes/twines are slow and tedious to spread around the whole group. It's obnoxious both for savage raiders and for casual players to upgrade tome gear so another way to get those materials prior to a new 24 man dropping would be amazing.
