You can take whatever you want at 30th; youve basically already won at that point. I used all your feat slots, though. Eat hardcore chips as your main food. Don't count on having many SSDs. You're gonna get body horror whether you want it or not. Crafting feats are generally not great (but some are and for some builds they are), and you don't have any particular need for any of them; check out what I got you instead. The main thing to look at is versatility. You can handle DOMINATING if you want to; its a very strong build. One of the bigger changes was removing three-pointer and some of your chemistry; you'll still have grenadier to help with flashbangs which you'll be using a lot, but dont rely on grenades for damage when you have an SMG which is better. Btw, use a bigger slower smg in your other hand and switch to it for the free burst from commando. Not too sure about your feat order, just take whatever seems best for where you are. I fixed your crafting skills, but didnt touch your subterfuge skills. You had to drop something so I got rid of merc since its mostly a luxury skill. Those few intimidate points weren't helping you much. You may not have maxed crit chance, but ambush will help make up for it and Ive been told smgs already melt shit anyway. As for psi, 3 will is fine for what you're using.
Get rapid reloaders and muzzle brakes for your smgs.
edit: just added escape artist instead of trigger happy; wont need super high initiative as a stealthy character
