On my server, technically 8/8, I am also 8/8 on another server thanks to world visits, I don't have to limit myself to 8.

I RP and write multiple characters. Only 3 of them are levelled and 6 are at 70, though I may keep them there.

But those three are:
Saefinn - my SCH/SMN/RDM/DRK
X'hayu - my PLD/WHM/MCH/DRG
Yesunova - my DNC/GNB/SAM/BRD/AST

But am only using Yesunova for endgame at the moment.
