I've never tried a character with Dex built. Personally I find that I can make up the aim by getting dex gear and aim scrolls, if you're not planning to PVP too much, I think free stat points would benefit you more going into STR.

I have a 25 SPR rest STR axe fighter, and I don't see any problem with that built.

It's hard to say what's best, because it would also depend in your gear and if you use cash shop items, but I'd say either full STR, or 25 SPR rest STR would be a safe built that you can't go wrong with.

(In case you don't already know, the 25 SPR is mainly for 5% crit rate.)
