Level 20 in Vana'diel

[UltimateSpamGrover]

I read somewhere that in FF XI, once you reach level 20 you MUST be in a party to gain experience. Is this true?

wrong! , thats from level 10 on, unless you want to gain 12 exp from a easy prey monster fighting solo

EDIT: Where's Lionx? (Hmmm.)

It's not that hard getting in a party, unless you're not a cookie cutter job like yours truly
