Possibly a good build?

Alright, so I'm pretty much a noob when it comes to playing the cleric class (I usually go for mage). Anywho, I was thinking I'd go 1:1 END/SPR until SPR was at 25, then go full END. I've also been thinking about doing pure END or pure SPR, based on posts I read a long time ago, but then I've seen some posts here mentioning STR. Is that really important, even if you don't plan on clanking?
I'm not trying to be just a healbot, as I do like to solo a bit at the earlier levels.
So..yeah. Any feedback would be much appreciated.
