To be fair, even though I'm a big fan of SB SCH and consider SB healers as a whole to be better than what we have here, I think the criticism of "spam filler between DoTs" still applies to then too. It was much less of an issue back then because the times on those DoTs were smaller and broke up the monotony more, or the job had other sub-mechanics to make up for it (SCH Quickened Aetherflow comes to mind, same with AST cards).
