The nen removal technique of the guy that was with Hisoka was a burden. Maybe Chrollo is not under Kurapica's chain anymore, but now he has to deal with that repulsive beast, so maybe Hisoka is just waiting until Chrollo gets rid of the beast so that he can fight him properly. That means, he may be waiting for Chrollo or the Ryodan to kill Kurapica or somehow force him to remove the nen.
