Hey, I'll critique your build, then show you some of mine
So here's what I think:
-stats: Stats are fine, stealth sniper builds really can do whatever imo, I'm assuming you also have 5 strength since the wiki erroneously states that dragunov still has no strength req, it's 5 now.
-skills: you probably only want 40 cryo, 30 psycho if you're doing a minimal psi build. This gives you electrokinesis, which is necessary when telepunch starts failing due to lack of skill, and the 40 gives you premeditation, for the free electrokinesis. High cryo is unnecessary, as stasis is irresistable!
Evasion is great but dodge is always sketchy. It's awesome, but so is skill points, which are hard to come by on stealth characters. This is especially true for snipers, as the only true need for dodge is if you get surprised, but with max perception, this should never happen if you have detection goggles while running around.
You're better off taking dodge to 40 and taking uncanny dodge, then ditch dodge, if you must have dodge.
So those are the unnecesessaries, some skills you might consider to replace them:
-throwing: good on every character
-lock&hack: great for questionable combat stealth builds. Sniper is somewhat lacking in combat compared to pistol dex builds
-traps: can somewhat make up for lack of L&H and is compacted into one skill
-mechanics: the one crafting to take if you don't need other crafting usually
-biology: up to 70ish is a nice "half skill" for anyone
Feats:
-shroomhead=barf
-hypothermia= eh... used to be goodish, not anymore. Now that psi is getting nerfed, hopefully it can get reverted with just a higher psi cost
needs:
-premeditation
If you want a more combat oriented character that can also snipe, go for a pistol stealth build, but that requires massive dex investment.
Anyways, here's some builds I've tried:
Tank builds-
"braindead"
9 str
9 con
10 perc (to 13 ish)
skills: whatever tbh, non-psi tank basically has infinite freedom with skills. I think I went triple psi anyways for the lulz.
critical feats: full auto, sharpshooter, conditioning
Notes: Dragunov in one hand, heavy assault in other.
"magic braindead"
9 str
9 con
10 will
skills: biology, electronics, triple psi, intimidation, throwing, chemistry bit of other junk
feats: condition, psi feats
Notes: Has trouble with bots, especially in beginning.
"psi grenadier"
6 dex
10 con (all non will points go here)
10 will (to 13 ish)
5 int
skills: throwing(not quite max), mechanics, biology (70 with synergy), chem (112),electronics, tailoring(not quite max) triple psi
feats: grenadier, conditioning, psi (considered the free bolt crossbow feat)
Notes: Uses heavy armor (lol). Has trouble with.... >>BIG<< bots
Stealth:
I've tried a few but I can never remember exactly how they go.
"first stealth build"
5str
7 agility
10 perc
5 int (actually went 9 for testing purposes, wanted to see how bad high crafting was. Is bad)
rest whatever
skills:Guns, throwing, mech, electronics, 40psycho,35 cryo, stealth, L&H, no evasion or dodge(!)
feats: interloper, premed, that electronics crafting one,+obvious perc
Also trying a melee stealth build which is doing awesome currently, although I've stopped since learning the new build is coming.
