Best DPS Attribute Allocation

[Faustus2]

So, I'm new to PoE mechanics... i'm more familiar with the D&D Attributes and how they govern to-hit and damage.

 

 

From digging through PoE2 youtube video's i'm learning that higher perception = better hit chance for all (almost all perhaps) builds and that higher dexterity is better than higher might for more damage output.

 

I'm also gleaning from the research i've done that there are diminishing returns for maxing this (Perception & Dexterity).

 

So, (and feel free to tangent but i'm specifically looking at two weapon melee) what is the sweet spot of efficiency for the allocation of attributes for a DPS character, while leaving some points to spread in con, int, might, and reflex for flavor, support, party roles etc.?
