Observations:
* Interestingly virtually all (if not all) the interrupts on VT mobs from melee were on knights. Some of them weren't even hit much.
* Pets were not interrupting Zuns and higher, but they were interrupting Quas and Zovs (mind you these are PoP pets even)
* PC bashes clearly interrupt less on higher level NPCs. I did find some bashes on Zuns that did not interrupt spells. (these are level 65 PCs remember)
* Now I know why air pets were used in VT instead of water pets.
