I'd argue that Ultimates don't even make the act of healing that much more difficult or interesting, as a rebuttal to Yoshi's dismissive comment. Think about it. Ultimate mechanics usually come in two flavors: chunk its targets down 90% of their max HP, or outright kill them for failing. You're still not doing anything interesting with your healing, not anything that lasts more than a GCD or two tops. Indomitability. Whispering Dawn. Back to Broiling.

Ultimates just make the mechanics more complicated and increase failure punishments. You can't heal through punishments that cause instant death or cascade immediately into a party wipe due to mechanic failure.

"Go play Ultimate" is the latest in the long list of "I've never played a healer after Copperbell" evidence tidbits from our fearless leader.
