Not to derail but one can cannith craft a very good ML 20 gearset, throw in some Cannith Challenges gear and maybe some old S/S/S stuff for niche builds and you can cover epics with only a few swaps (mainly weapons) until level 29. Now with sentience you can really buff a crummy weapon and that fills the gap.
Again Please make artifacts crummy and let their power be in augmentation not bloated stats
