After viewing and partaking in various threads in concern to the difficulty of raids and trials and alot of thinking on the matter I think I have thought of a solution.

You have your people that say 'the content is too hard' and then you have the people that claim 'the content is too easy' right and trying to come up with a happy medium can be challenging if not near impossible.

Release something like the arch angel fights from Final Fantasy 11? Sorry I am pulling ideas from there simply because thats the biggest online game like this that I've played. This idea would also be similar to the Diadem except in a raid and trial format.

Do like a 4 tier thing where players can choose their difficulty level.
Like if players want to do the 'very tough' difficulty they can and not have to go through the first 3 to do it.

Do the same rewards for all the difficulty levels but set the drop rates according to the difficulty level, basically all 4 tiers would be the same but set to accommodate the differences in skill levels, casual players, and the hardcore players but everyone gets to have the same experience.
