They have options for min ilv etc in the duty finder. No reason to force everyone to do everything min ilv everytime they want to do a roulette or old dungeon/raid/trial/etc. Lot of the time for wondrous tails its easier to do all the lower ones solo and only do the higher ones with party. If you want to do content when its harder or at its hardest do it as it comes out instead of complaining its easy 10 yrs after its been out. Dunno about other people, but i would rather not be doing x or y dungeon/raid/trial for the 600th time at min ilv 5-7yrs later because someone thinks everyone should suffer.
