Shells: I may ask my old end-game shell to take me back but after being gone so long without telling them I don't really deserve it. Also, I don't really have the time on my schedule right now to support them like I had the time before (new job, new family, etc.) But they, meaning BOL, would be my first choice. BOL is a great shell for anyone who gets accepted. Otherwise, I guess (after I get my gear caught up a bit) I'll be open to other shells willing to accept me and my schedule.
Also, since I do not have a shell yet really, for now I'm open to helping people as a ronin mercenary. Just give me some gil, enough for my time and expenses, and I'll help you do pretty much whatever I have access to. I am a 75 NIN/WAR but I alo have some other jobs which are decently leveled. I'll pretty much tank any NM, Summon, Job Quests, AF Quests, etc. that might be difficult to get high-level help for because they're busy in sky or sea.
