A few problems I have concerns about:
FC's/Individuals/LS's selling EX mode instead of helping- Players dont gain experience, and people lose chances.

Solution: pls create some rule to help us be more of a community.

Players requiring ilvl's that are too high for progressing players. Seems the "high end" players are separating themselves.

Solution: Create a max Cap on ilvl requirement for certain dungeons, so that people dont filter out lower ilvls and halt any chances of progression.

Longer discussion:
A look at Party Finder lately has been making me saddened on my server Ultros.
Requiring ilvl 75-80 for ilvl 61 Ultima.
Requiring ilvl 80-85 for Extreme modes; Garuda is ilvl65. etc etc.

I try and try again to promote * Helping * others, instead of selling help for Gil. This has been an epidemic since Extreme modes have come out.
