Biggs I have to agree with alot of what you said, in this it's entirely to easy to jump shells for just what you want, and of course getting people to stick with a single shell is gonna be a pain. Leaders from all your shells are gonna be wanting you full time.
On the other hand, being able to see a social, and an EG/Event shell wouldn't be all that bad. In XI I dropped my social shells because my EG shell would be on, I'd miss requests for help and people would think I was LS hopping when I in fact wasn't, I was just in an event that once finished I woulda been there to help w/ w/e.

It's kind of a tough situation, on the one hand, people will shell hop, on the other if you have more than one shell and are on one for an event people may see you as shell hopping when they see your on and not responding.
