Pvp if you don't have a BLU to farm with(not sure which run they'd farm, assuming Vale if that's the easiest though).

Sadly I'll be doing pvp because my BLU is only level 44 and I don't have enough spells on it.

Prae also doesn't look too bad if you have things to do and you can time them during the cutscenes(although sadly not as afk as it was before the changes).
