You've run some great exp-campaigns that enhance chains or greatly affect base exp/cp and these are great and fun and fantastic and the parties are awesome.
And then the campaign goes away, and what should feel like a great party feels mediocre at best. A lot of people, wanting to maximize their invested playtime, won't CP outside of a campaign so you end up with sub-optimal setups or people not geared enough to be there.
The best parties can clear 250-300 JP an hour during a campaign, so half that during offtime. Lesser parties are doing doing 50-100.
I'm an old player. Like many people here I remember when 3 merits an hour was a great party that you wouldn't leave if you could at all avoid. Remember the days when someone earned a merit point and everyone stopped to say grats/cg?
Then Abyssea came out and obliterated the best bird parties.
It sets a new bar that just feels disgusting without. I'm not at all asking for exp-campaigns to go away. I'm asking you to make them permanent. No longer a campaign, just part of the game.
