If PCT could only paint with a target, you have 2 scenarios:
1. PCT has to pre-paint before the boss goes untargetable, potentially failing a DPS check.
2. PCT has to paint once the boss becomes targetable again, thereby either misaligning its raid buffs with the rest of the party, or forcing the entire party to burst around PCT.
This is not a good solution.
