Good factions challenge

I got to the palace mission just now- henched the dragon mission and went in to lay the smackdown on shiro.. found the palace mission is timed! took me 3 tries- first couple failed but finally came up with trick or 2 and completed it with the henchmen.. you can see on the last try the timer was on it's last leg was wondering if anyone else beat this with henches, the guys in imperial did'nt believe it so glad I took some screens.. this is pretty tough with the timer going- no way to really small pull groups and make the time limit (died once pulling that whole room before the palace doors).. anyways here's pics
