Im in the same boat as you. Im in a great FC but their top 3 raid groups are 6+. I am looking into making a new one. But I am stuck on 5 and titan ex right now. But ive been playing about 2 months and thats fine.

DO NOT change the difficulty. Maybe implement an in game audio chat to make DF and PF better. Or...offer incentives to those who run learning parties and see them through to a win. Like, u only get the reward if at least 3-4 players beat it for the 1st x. Or FC rewards for members beating content.
