There is no better use for a Tank/Healer LB than to mitigate/heal such heavy burst of damage.
The SMN burst combo is not a "standard rotation". It's a big burst only available every minute which completly shuts down the SMN after doing it (would it be successful or not).
Besides, no, you are completly wrong when you say that SMN have great ranged sustain damage. DoTs are a joke to heal through and Ruin II spam wouldn't even kill a paraplegic slug. Plus, with the lack of stacks, you can't even Bane/Painflare, making your overall damage completly worthless. Also, since it's magical damage, they can't even interrupt healers&casters.
tl;dr: SMN is a glass canon with just a burst every minute. This kind of burst is arguably the major reason why Tank/Healer LBs and heavy cooldowns even exist.
