Only active Captains and Vice-Captains are limited.
Since Urahara and Yorouichi (and probably Isshin) are 'rogue' they aren't limited.

Ichigo is a subtitute. Ikkaku, Yumichika and Rukia are seated shinigami (or level, in Rukia's case), so they aren't limited.

But yeah... the dolls messed up the fight.
