I'm taking strength up to 7 by level 24, no higher than that, so metal isn't in the cards unless I move some attribute points around.
I've noticed that metal armor is the standard pairing for sniper+assault rifle, but I'm trying to focus on avoidance and stealth instead, so it's not really a good fit here. I need to be at max health to fire off 3 Electrokineses, and that'll pretty much never happen if I'm in metal armor, since I wouldn't dodge anything and I'd never start first. Similarly, the point in dex is a marginal increase in initiative, which is helpful if I get ambushed. Putting it in con doesn't really do me much good, since I'm trying not to get hit in the first place.
First of all, Styg confirmed max CTH malus from difference in skill (when your dodge/evade is twice theirs) is only 60%; dodge means you'll still get smacked 35%(assuming optimal range) of the time. So pure evade/dodge as an absolute defense that is completely out of the question.
To make up for this, players choose from armor types and a shield, which is determined by their build/playstyle/requirements. Crafting players can make the lighter armors work, for a cost, or the super heavy armors even better. If crafting, a high quality supersteel fiber infused Leather vest gives powerful bonuses, low armor penalty (if not ancient rathound) and damage mitigation equivalent to most mid-weight body armors. I think everyone has heard me extoll the virtues of heavy SS metal armor, so we'll skip that.
Another problem I see with your build is that SR and SMGs actually have a fairly weak synergy, not only do SR weapons not benefit from auto weapons feats but requires critical feats to maximize. SRs have base 5 STR req, while SMG builds are really maximized by 16 DEX builds, and benefit much less from Perception than SR builds. SMG/SR builds are workable, but requires quite a bit of minmaxing, and is less flexible (Attribute-feat-skillwise) than an AR/SR build.
Even worse, you have a 3 WILL psi build. Splashing in some psi-based CC on a high-CON Juggernaut build is okay, but on a 3con build you'll die to almost anything for minimal gains. Most psi-spells are not very good on correctly optimized SMG builds anyways, because you will kill all your opponents in 1-2 turns (6 bursts in one turn if blitz or adrened with 7.62).
I
could splash psi on a 3 constitution run, but not for my first game, not for Psychostatic electricity, and most definitely not on a 3 willpower build. Add in the difficulty of attempting an SR/SMG build, and the points for Attributes, Feats, and Skills don't exist.

Your build is poorly optimized, and will have some trouble in the late game without permastealth-alpha strike shenanigans. If you enjoy walking everywhere at a snail's pace, having to save scum, and occasionally dying anyways in 1 hit from a sniper, you can continue and still clear.
Otherwise, I reccomend you restart.
