The last days i did some nice Ruby ex runs, ppl farming weapons... so they join with 480/500 gear but 430 wep...

And i had a Holminster run where the heal and dps had some 290 parts and 365 wep... no fun. I got in there as replacement tank, 26 min in they havent even beaten Tesleen...

Yes it needs to be changed, even on premade you should not allow a lower level then the duty. Also the min. level for the highest unlocked duty needs to be enforced for rouletts do ppl cant cheat anymore.
