Is SPR useless if you want DPS?

That's what I meant, I didn't go into details about the equipment though. The point is - you get critical percentage even if you don't add anything to SPR. A character with 25 STR instead of 25 SPR will have those, theoretically if you both would do 20 attacks he would do one only one critical hit less, but each of his attacks (including critical ones) would have 30 points damage boost. That's what this all is about, it seems that those 30 points are almost always better (especially in the beginning of the game).
