On Scholo, there is no cookie cutter talents, you are better off changing them from boss to boss.
Pre-pot at the start of the instance. For the first boss, start with FDCL+ToF+DS, since usually you pull all the Warders (I think that's the name) to the boss, leaving 4 adds to multidot during the fight. Just drop the FDCL procs on the boss.
After the first boss change FDCL to SWI. For the trash between 1st and 2nd boss, you will only Mind Sear and DS, while keeping dots up on the Warden.
Second boss should be pulled as the adds are about to die, to get benefits from ToF. You also should be able to pot during this boss.
The trash before Rattlegore keep the same talents, since it is just full AoE. Don't forget to help the healer out with Mass Dispell for the debuffs.
Before Rattlegore change ToF to DI and DS to Halo, to maximize single target on the boss. You also should be able to pre-pot and repot for Rattlegore. Don't use any other potions after Rattlegore before pre-potting for Lillian.
After Rattlegore, change before to ToF and DS, since you will just AoE all the trash. Keep in mind for that part that you might need to use a Life Grip so the tank won't die to the massive damage. (Talk that with the tank prior to it)
After the trash dies, swap ASAP from ToF to PI and DS to Halo. You can Pre-pot for this boss. If you fail, however, your pot will not reset it's CD before you need to have your invisible pot up, so be aware of that. In order to be able to get the burst on Lillian, be sure to have the group positioned in the corned of the room, so she has to travel the most until reaches the middle of the room AND you will be in the perfect spot to Halo. Stock up 3 orbs for when she reaches 50%, then pop PI, recast VT and SWP, Halo and DP, from there just burst her.
Depending on your strat for last boss, the talents will change. If you're killing the adds instead of letting them explode, ToF is a picker there, otherwise, keep DI and SWI for it. Also, if you're killing the adds pick DS, but, if you're letting them explode, the L90 tier is useless for this fight.
Good luck with your CM run!
