I dunno. The major appeal to me of the JLI is its collection of loveable losers who still manage to do some good even though the usual story involves low stakes or spends most of its pages revolving around how they sort of can't stand each other. Ideally, the Justice League proper should be a global force anyway, obviating any need for a JLI if the book's just going to be regular old superheroics. (And Booster Gold without Blue Beetle seems kind of pointless; Giffen and de Matteis pulled it off for a little while, but the best part of the run really is when Ted's around; of course, near as I can tell, Barry Allen wiped Ted Kord out of existence; very sad.

But hey, I didn't pick up JLI, I could be totally off-base.
