I spent a few hours killing Greater Colibri tonight as a NIN with two Katana merits and 34 Acc in my TP build. I was a career BLM&SMN who leveled NIN so I don't have the uber gods gear etc that the other people did (a Ridill War, a BB Mnk in that party) and am still kitty pantsless.
I tried to first voke every mob, but sometimes it wasn't up so I'd Hojo and hope somebody else got a crit or three to grab hate off the BRD. Neither the BRD or RDM got killed or seriously maimed, so I think I did ok in that regard.
I had a stack of sole sushi and a stack of mithkabobs. After a few swings I usually lost hate, so other people's food got ganked more often than mine. I didn't get any parrying skill ups like I usually would in parties with crappy DDs either. I couldn't parse my acc as I'm on PS2, but it was pretty bad without sushi up so I ended up going through all my sole with some kabobs left over.
I've been in several other parties there on the birds, and unless the DDs are really good they sucked pretty badly. My NIN can do ok at the Nyzul Isle party in the Mire, but I need lots more acc before I'd be comfortable doing colibri with meat.
So I kind of agree with both the "ur nin is gimp" and "ur DDs are gimp" comments.
Hopefully I wasn't too long-winded and stupid.
