I'm definitely not advocating what this person did, and being 'anti-SS' is just stupid. However, WHMs do need to learn that you don't need to SS the whole group before *every* fight. A lot of damage done throughout even the beginning of the fight is relatively harmless, and will break the SS within the first 30seconds of the fight (Raff's chains). At the most you are saving a regen's worth of curing (instant cast), vs. 3 second cast x6-7. Just SS the tanks and move on. It adds a lot of time before each pull to full SS party members, for minimal to no benefit. Not only are you waiting the whole cast time, but also cutting your MP regen in which the Tank has to wait for full to pull.

TL, DR; The SCH sounds stupid, but you don't need to SS the whole group every pull. Time adds up.
