I don't think il ever reach lvl 70 so il just put 25 spr. and rest in int.

Noo the other way around.. dont go SPR if you wont get to lvl 70...

It's not useful for lvl 1-69....

I play as a solo cleric probably 98% of the time. My build is currently 50 Str, 25 End, and 10 Spr. I started as a pure end, then moved to the strength as I started figuring things out. I am adding to the Spirit now up to 25 to get the Crit damage bonuses. With this build, I have no problem with assisting the few times I choose to party, and I also kill pretty well - Soloing Giant Orc Captain was no problem for me at L66, and I was 2 hit killing Giant Sparkdogs at L68. Of course, you can alter any stat decisions with green or blue weapons and armors and by enhancing your equipment.

There are 3 basic cleric builds. As a support cleric you want high defense which is spr and end. As a clank (solo) you want str and end. A hybrid build would be spr, end, and str. 25 spr 50 end and the rest str is where you want to go and these are the stats to look for in gear.

Build str in increments of 5 points as there is a bonus because each point is worth 1.2 str and the .2 does not apply till the 5th point. That is, 5 points = 6 str

In all cases you will want 25spr (+5 crit and increased mdef) and 50 end (block rate) minimum eventually.

So for my mage since i wont ever reach lvl 70(im 90% sure of it)il be FULL int?
