Vercure and Clemency are nice utility for solo playing, but are hardly of enough consequence to remove healers' relevance in group content. There's little need to get rid of those skills. If anything, I'd have SE actually sit down and either make SMN's pitiful Physick strong enough to matter for solo content (link it to Int or SOMETHING) or otherwise just outright get rid of the skill. I can't even justify keeping it on my SMNs bars, it's that useless, certainly compared to even Vercure let alone a proper healing spell.
