I personally did Card Bosses and saved up the booklets until 2x and sold the SLS.
Go do card bosses. It's time consuming but easier than ws and the profit is bigger.
No it's not, all you need to do is kill pwi bosses that die in 3 hits.
Holy path on genie solves everything.
If you can dual client, just get one sin to 140 (primal or demonic gear) and a few 110 level sins following the main in stealth. This way, you can get around 4 sets of card bosses (excluding GV) in 2 hours. 4 sets = 48 SLS. 48 x 110 (or 120) = 5k+ So, it's profitable and really easy.In case you don't know what cardbosses are, check out http://www.epicpw.com/guides/card-boss-guide
