While I can see the utility... for a Paladin (bloody Shield Oath being given at the wrong level), every other class would actually benefit more (to the party's detriment) from keeping their leveled actions and traits. As in the cited example above, new tanks would be woefully underpowered against a Coil-rated DD or Healer. Hell, they already are and that's without leveled actions and traits. And what's worse, these players often don't act like they're capped when in a lower level dungeon and attack every mob as if it was like level. Having access to all their leveled actions and traits would turn these dungeons into end-to-end cluster fu~~s. No, level sync is working as intended. Learn to throttle yourselves, your tanks would love you for it.
