I like this idea. Its now an actual thing to have a personal limit break (PvP Slaughter) so I think/hope its only a matter of time before we get our own limit breaks, at least while solo. What would be really cool is if they could, eventually, only have personal limit breaks and then for a group mass limit break you have to chain them together in a particular order to get a particular result. Kinda like the FFXI skill chains. That wouldnt be till like 4.0 or beyond IF they even decide to do something like that. Fun idea to entertain though. But personal "adrenaline" bars for solo play is something I would love to see, only if everyone gets a DD limit break though.
