I shared this story before on the topic of ilvl and I will say it again, yes please, please add ilvl requirement to MSQ dungeons.

Until a month or so ago I, honestly had no idea that's not a thing. Shame, I know! And so while leveling AST in my scrubby shire gear and some dungeon drops I happily do a level roulette per day and constantly getting the lvl 50 dungeons and sometimes 60. I'm thinking it is because of my ilvl. Now one level left to 70 and imagine my horror when DOMA FRIGGIN CASTLE popped. I was horrifed. I gave heads up to the tank and dps, appologized and lucky for me, they were very understanding. No deaths, smooth run but it did make me push my full toolkit and if the tank didn't do small pulls, I'm sure I wouldn't have managed it.
Lessons were learned that day.
