ECO Collab is actually a fun dungeon. Heaven is EZ with Kirin, so I'll farm that after I clear the rest for stones. I wouldn't mind a max skilled Forty since he'll be great for balance teams. I also would LOVE max skilled CTW.
Lakshmi is worthless, so I don't care about her. Loki skillups would be nice, but completely unnecessary IMHO. And Drall skill is sort of dumb, too. He's getting the Attacker sub, but I haven't even bothered with an attacker team yet. Physical, Balanced, Devil, and Healer are really all the rave in terms of 9x teams. I guess Dragon could be there after 6.0, though.
