Why does SMN have Physick?

[Shurrikhan]

I'm glad they haven't yet. I wanted to level a healer so I could do the role quests in ShB and having SMN along as a bonus was really nice, especially given that I came to really enjoy how the job plays, and I think it will in fact end up replacing RDM as my magical DPS.

That aside, yes, physick is bafflingly useless. I wasn't entirely convinced of this before picking up the job; I thought, "it has to have some utility, right?" But no. It's just there.

Just as all damage skills on healers were originally useless without Cleric Stance. Yet they changed those to work off Mind, just as Vercure works off Intelligence. So why not do the same for Physick?
