If SE would give smn cure 5 then people would use them to heal.
This is like "If we give a white mage Firaja we will use them to nuke."
You're saying they should give SMN something they have no skill for and is not even part of the job itself. Cure I-IV comes from the SUBJOB. Tell SE to make cure V level 49, then you might have a point. But cures will not be added to summoner (except as avatar abilities, because that's not directly part of the job.

People like GreatGuardian & DebbieGibson (kiss it where the sun don't shine if you don't like being called out on your BS) are PRIME examples of why BlueGartr and other such forums (Allakhazam is coming really close, as well) should be stripped of their Premier Site status.
BlueGartr is NOT a premire site (thank the heavens).
