Your Cross Class spells are perfectly suited for situational use. I actually tested utilizing Queling Strike and there was no discernible reduction in hate generation by my nukes.

Currently, my THM's CC abilities are:
Gladiator: Sentinel
Pugilist: Featherfoot & Second Wind
Marauder: nope...
Lancer: nope...
Archer: Decoy & Chameleon
Conjurer: Stone, Cure, Raise, Stoneskin, & Sacred Prism

For 99% of what is out there, this should suffice to fill your needs.
