Hmm true, we'd just tap when we need a shard and let our healers deal with it.
Flat, boring bonuses often turn out ot be the best in practice, so I'm okay with boring set bonuses. Better than getting some outlandish new tech feature that is either buggy or doesn't actually increase your damage in any significant way (thinking Class trinkets here for some classes).
First tier I'll happily take some boring, but working and significant bonuses. Let the fancy stuff come in a later tier when they are not also working on a whole rest of an expansion.
