Guild Wars 2

Edit: To take this one on a level worthy of discussion, see my second post below.

I honestly think that’d be fairly stupid and pointless. If someone is getting 0 drops then it would just be a waste of time for that person. If they’re looking to have a fun time then they could just do whatever lvl they are in and get actually get drops.

It is for the challenge. No other reason to play higher levels except the challenge.
The drops stay the same, be it a bug, but drops do not improve with difficulty at the current time.
Let people play levels together with their friends without hindering the progress of some by replaying over and over. The dungeon itself is designed to stop you from progressing, by difficulty of the mobs, not difficulty of finding groups.
No reason to let people not play higher difficulties even if their own is lower.

If I were here to make a serious suggestion:
Give loot equal to the current level someone is on, upon completing the higher difficulty, up that level by one.

Perfect solution. People cannot farm more by joining higher difficulties, people find groups faster, no one loses, everyone wins.

Loot isn’t the same, dev already said it scale with the fractal scale, each 10 new level the drop have better/other drop table.

They said it, but they stated it is bugged along the lines somewhere.
And as I was saying, give players from lower level tiers loot for their current max level.
