Most important stats for a Rogue? (POE1)

I have heard Rogue isn't the best realized Class in POE1 but I've been oddly taken with the idea for a while now.

I was just curious though, for a dual wielding Rogue who focuses on things like Wound damage and other things, what is most important? Does Might effect things like the Wound damage from Drawn-in-Spring?

I was thinking of playing an Orlan so should I go for that 20 Perception from the start?

Appreciate any help you can give. I'm not going POTD or whatever; I'm not nearly good enough. But I'd still like to not screw myself over by building badly.
