The current dungeons aren't even that easy, the thing is people are too overgeared for them, that's why the only solution here is ilvl sync.

[sidestory] A few months ago I did Haukke HM with a party where the average level wasn't higher than i55 (only my healer was i90), we wiped so many times to the last boss just because we couldn't meet the DPS checks when the adds spawned, fast forward two months later the same party did the same dungeon from HL roulette, we hit an enrage because we DPSed the main boss way too fast, our WHM had to sit there and not dps to avoid wiping again.

Doing hullbreaker or tam-tara hm with a full i80 party is really far from a faceroll.
