So Ive finally found a max level job I really want to progress beyond what I can do in normal content. My greatest barrier to entry ( I think ) is the anxiety of messing up as a new person and wasting 7 other peoples times.

TLDR Where should I start? Doing some older ex synced? Does party finder have a way to find groups for new raiders who are happy and willing to wipe over and over to learn and not expect completion? Or should I watch how to videos on current Pandemonium stuff and focus on that instead? What is expected of me to have before I even start? Raid consumables of some kind? Potions? Certain materia's or item levels? (side note, I still dont understand materia...at all)

I really dont know how the social structure of raiding in this game but want to learn so any advice or direction to helpful websites for noobies is appreciated.

I really love this game but I want to do more than level jobs to 90 only to stop and level another. That isn't going to keep me engaged forever no matter how much I enjoy the game.
