Why ? Do MNK, DRG and NIN eat cleaves ? Being in melee range doesn't require you to be in front of the boss. It just means you'll have some weapon skills that will help you builds healing power or ressources that you'll spend to heal the party.
As for fast healing, if it uses TP instead of MP, we might assume that all those heals would be instant.
