Bossing for lvls post bb

Hm, I have a bunch of chars so getting cracks isn't a big deal, but pap exp is looking kinda weak now especially with 2x getting the boot. And I'm not sure if my gears are up to snuff for a zak solo. I know I can duo w/ my friend, but if this is as good as it gets I think I'll just stick with my current builds. Only my shadower is making me consider different builds, f/p and aran are pretty straightforward. But I think I can hold off on assassinate and just get bs/greed for good training and solid bossing. Yeah I'd rather have the option to grind or boss instead of having to boss until I get to 14x. Thanks for the info.
