I just went into a Champion Quickplay weave for the first time, after gearing up for a while - Athenor and Amulet nearly level 30, and weapons around 20. I had someone join who was playing the mode for the first time! That meant they’d have everything at level 1, on a Champion quickplay.
Through no fault of their own, their participation was abysmal. Please restrict joining quickplay difficulty based on athenor or amulet level, so people will actually know what’s going on and have built up their characters some before they dive in at a higher difficulty and discover they’ve been reset to level 1.
