More characters should have thrawn effect on raid bosses

Khorvog_Karbossa

Since thrawn has unique effects that would be nonsensical in raid (speed up on basic, fracture 0% speed), we also got secondary effects on those for use in raid. This is a great mechanic that should not be over used, but some named characters should also get the treatment.

Examples:
Director Krennic should inflict unresistable tm reduction rather than ability block on leader, and his special should deal bonus damage plus protection regen on empire allies
Kylo Ren Unmasked: halt should be unresistable turn meter reduction
Darth Sion: Pain is stackable
