Yeah it will increase the stat. The real question is, once at 60, what is the precision to crit ratio? Tier 14 Emeralds give 100 Precision. If you slot them in 11 pieces of gear, that is (1100 Precision + gear)*1.4. Critting like a madman I would think.
On the other hand, 1100 Defense could be pretty insane too... I wonder how much that reduces damage taken.
I hope they don't bring in some lame diminishing return mechanic.
So getting 100 Precision and casting Energy Armor-Alabaster would net you ~6.69% more crit chance, almost 25% crit is pretty good. And you would need to hit about 300 to get a 50% crit chance. Hmmm... so 1 Tier 14 Emerald is worth ~16.73% crit.
So 430 Precision is the magic number you want to hit for a wizard. You would need 3-4 slots for Emeralds (I would say about 3 tier 14 emeralds) + your personal precision stat to hit that number. Energy Armor-Alabaster will bump it to 602 = ~100% crit chance. (Assuming no diminishing returns)
So the only things that don't scale with level is damage from attack and life from vitality. I find this pretty lame. At level 60 you will be straining to get higher precision just to crit a tiny bit. It's silly that a low level character with crap gear could have a higher % chance to crit than a level 60 character with decent-good gear. Same goes for Defense; you'd think that when you equip a huge beastly breastplate it'd protect you a whole lot better than that cloth tunic did when you were level 5.
I understand that they don't want crit chance and damage reduction getting out of hand, but it certainly seems that they should change it so that the formulas lead to a little higher numbers at level 60 imo.

Then what's the point of this attribute ? They could just take it off, same result. I mean, it doesn't make sense at all if they don't want us to focus on a single attribute, or denigrate another.
Well, essentially you will have to trade ~1100 precision for ~1100 attack that you would get from Tier 14 gems in every slot. Possibly more, as there are likely multiple sockets per slot, but 1100 is a good number to think about.
Is 1100% more damage better than a ~10-12% chance to crit? I would think so.
Precision would have to give extra crit damage to match up to that. Even 100% crit chance wouldn't match up to 1100% more damage from attack.
Of course, potentially on crit effects from some of the skills could be powerful, but they don't seem plentiful or powerful enough to make up for trading 1100% damage for 12% crit.
So yeah, I don't think we have enough information about what Precision actually gives you.
seems like attack and vitality has more value and ofcource more logical but about this two:
Precision: governs the chance that a character will make a critical hit in all attacks, physical and magical.
Defense: governs the amount of damage a character takes from all attacks, physical and magical.
the word "governs" has to be explained..
I'm pretty sure that Precision and Defense both work like in WoW (I know, I know, shut up) i.e. that as you level Precision gives less crit chance per point and that armor has a formula of diminishing returns as you get more and more armor. i.e. there's now way that 600 armor reduces damage to 0.
However, keep in mind that Attack value increases your BASE attack value, so 100 more attack is modifying your base attack damage, while precision does more crit damage based on your current TOTAL damage value. So there's very likely to be a synergy there somewhere that makes one more point of one, more useful than the other. I just don't have enough specific information yet to confirm which is which.
