I'm not surprised Kid Flash and Robin are kinda being neglected, since they've appeared in animation multiple times (Dick more than Wally, but still). This is M'gann and Conner's first appearances in animation, Artemis' first regular appearance (cameo in TBatB), and Kaldur is brand new. So they show more of them and make us wait for the more popular characters.
