Once again, its supposed to provide an extra incentive to those who want a challenge, not those doing it to cheese cosmetics. Once they do it they will be done with it, but others would still like to run ordeals to test limits. This was the main issue before as both Luci and A and E had become trivial once you had experience enough to run and knew all mechanics, how to get best relics and where to go in general.
The impact a few lv 12 "slackers" as you claim is minimal and yet to be felt, as I mentioned equal if not less than entering a bad or low pop lobby.
Again, I fail to see the relevance of this, nor your outrage about someone cheesing a run to get cosmetics. If anything ordeals allow you to learn mechanics, spacing, pacing and resource management better if you actually play with them.
P.S. Sorry to be a bit harsh, but this honestly annoys me as a topic, especially given the non-productive and borderline provocative replies from you, so I decided to send one back too. I don't think I also have anything else to contribute, so good luck.
