It's been said a dozen times over, so I'm not going to beat a dead horse (too much), but Mythics were stated to be artifacts that improved job specificity. Yagrush is a perfect example. They're not meant to, nor were they ever intended, to be supreme damage-dealing weapons. The only thing that's completely bogus about Mythics is that they're impossible to get. Nobody does Nyzule Isle, ZNM, Einherjar or Salvage anymore with any frequency. You couldn't pay people to help you with that crap for as long as it would take to finish a Mythic. SE did an exemplary job of killing that off indefinitely with the introduction of Abyssea. If anyone is to "fix" Mythics, the requirements to obtain them must first be examined and reworked to fit in the current metagame. The weapons themselves are fine. If you built a Mythic to deal damage only, you made a serious mistake. Dealing tremendous damage is solely the purview of Empyreans. It should also be within the range of Relic weapons, but until notable adjustments are made, Relics will just be squatting on middle ground in terms of usefulness and overall damage capability.
