I'd agree id see so many recruitments in wc about wed take everyone but sins there closed I'd don't understand isn't a lot of sins in a fact is a good thing
Hence why my sin is for farming purposes and my wiz is for that closeted violent side of mine.
I mostly multi-client BHs and TT -- Sin, Barb, Cleric, HA Veno. I put 3 alts to Follow Sin, while she clears to boss. At boss, Sin is handy because she's 'set and forget.' Sin (for PvE) is ungodly easy to play and I think that's the reason they are so popular.
