I do not agree with the raise of the difficulty in behests.
They are made to provide easy EXP and that is what they do.

I do agree with the harder boss suggestion and I do agree to "slightly" raise the overall difficulty of behests, but a raid boss at the end?
No, I dont wanna waste 30 mins of my time there (or propably more) if the end reward isn't worthwile.
If they make the reward worthy, then the point of behesting will not be EXP focused any more and it will become the said reward.
That means that when the majority of people will get that reward then they will stop behesting, unless the EXP is REALLY good.

Bottom line I agree with many posts but if its about the raise in difficulty make it reasonable and not your 30 min random raid dungeon.
