THAT! exacly will fix a lot of issues in my opinion, (plus SE adding actual content worth spending your time farming, say, hard modes that are actually hard and you need to learn the encounters and such, that cannot be pugged with duty finder, as to make it more serious, and tighten the community. (AND YES, there will always be elitist assholes, but there's only so much SE can do this way, it is also up to us to form up as a community)

But with this, most of the mindless grind everyone hates so much will be gone, atleast in some way, yeah, you'll take twice as much to finish the dungeon, but you'll get 3 times the reward you were getting before, hence making it a 33% faster and more rewarding, you can farm materia spiritbonding items etc. do not however over add rewards, like those 1600 gil and such, though gil needs to be rewarded, you have to balance it carefully due to not break the economy.

damn the 1000 limit, is too short... well I hope you guys got my point tho.
