I won't go over phase one as it sounds like your group is having problems with the phase 2 portions of the encounter. As mentioned above, everyone and I mean everyone has to get to the outer ring pronto when he transitions. Your raiders have to be mindful of where everyone is and where they are so if they get picked to the fixate, they can move accordingly. We have our melee dps on the jailer near where we are unlocking the prisoners (we do poison first, ice second, fire last). Our ranged dps stands on the border of the outer and inner ring so that they are in range of Thok most of the time. They are also stacked up relative to where we will stay when we start phase 1 over again after the sacrfice so there is little movement. We generally take his fixate to 7 stacks before we unlock the gate so he hits about 9 stacks (which starts to move faster than you) when the RP is almost done.
Take the fight one phase at a time. It will take practice and the full attention of your raiders. You are not responsible for making their decisions. They should know what is going on around them and not tunnel vision the boss. Really it boils down to positioning and situational awareness. These two things will make or break this fight.
Best of luck to you and your group!
