I just found the answer to my question, "There are no role requirements when entering as a full party. However, parties with less than 8 players must adhere to the standard composition of 2 tanks, 2 healers, and 4 DPS." Just purchased my first ticket, and now I'm like.. wondering if I should purchase a token to transfer servers. That way I can set up groups/speak with individuals for a change (since I'm currently playing on a J server, and I don't speak J).

*facepalm* I can't do anything as a solo player when it involves end game items that I'm interested in >_<
