What content has gated you, and for how long?
Primals. Since 2.1 came out.

Why are you stuck here?
I need to defeat King Moogle and Titan HM. I like to run primals with members of my FC, but not everyone is online at the same time. I could join a party finder group for learning, but I haven't done it because I'm afraid someone's going to be a d-bag about it if I don't perform perfectly. I get this feeling that a lot of groups go "Oh crap, there's a summoner," since most people seem to prefer BRD or BLM for ranged DPS.

Are you upset about this?
No, I'm not upset. I'm just jealous that a few of my FC mates have relics already.

Should any changes be made to the content to accommodate you and players like yourself?
No, I don't think that anything should be made any easier. People have passed the hard content so it's doable.

What kind of content would you like to see added in future patches for you to enjoy?
More dungeons!
