It's really easy in expedition to reach 100% crit chance
No, it's actually quite hard to reach 100% crit chance without either Ambush (highly situational, even if you use molotovs to trigger it, still a good pick for many builds including snipers though) or Survival Instincts (I don't consider running around with <30% HP to be a good choice).
other weapon have easier time getting there
Walk me through the math then, because I fail to see how crossbows or energy pistols (which you compare sniper rifles) have an easier time with stacking crit chance. My sniper builds end up with at least 59% crit chance by the end of the game: 10% base crit chance, 7% recklessness, 7% scrutinous, at least 15% from seeker goggles, 15% focus stim , 5% hardcore chips. Energy pistols will have a hard time getting scrutinous if they dump PER as you suggest, crossbows will have a hard time justifying the use of seekers instead of smart goggles since they can't compensate for lost damage with specs as much as sniper rifles can. If I really wanted to go for max crit chance at the cost of gimping myself in other areas, I would also go for the 10% from digital scope and most likely another 10% from infused rathound leather armor, for a total of at least 79%. Sniper rifles will again have an easier time justifying the use of a digital scope compared to crossbows because they get the scope slot for free and can use smart modules, energy pistols can't use scopes whatsoever. Plasma pistols get 15% crit chance from Steadfast Aim though, which is nice.
5 AGI, a crossbow can just take Marksman spec.
5 AGI is not a high requirement and it give access to sprint, which is argueably one of the most useful feats in the game in general. Marksman spec doesn't interact with move penalty at all, it merely gives up to 5% bonus hit chance. You will still suffer from 10-15% move penalty if you don't pick Strafe.
Again 100% crit is more meaningful to other builds because it pushed them into the same one-shot one-kill zone as sniper rifles, and snipers need to make some sacrifices to get there.
No build gets to 100% crit chance without making serious sacrifices and/or it being situational. No build gets into the "reliable and frequent 1-shots" zone snipers are in. Snipers can settle for relatively high crit chance with no sacrifices at all.
Blitz had 10 agility requirements
Yes, it can be worth it. I don't really use Blitz myself on snipers though, I find it overrated.
Snake people cocaine is not exclusive to sniper rifles.
And that's relevant because? What matters is that it pushes snipers into the exact sweet spot when they can shoot 3 times instead of 2.
Both of these have long CD and/or bad side effects and have no meaningful benefits against 20+ savages/spiders/burrowers
There's no AP buff that doesn't have a long cooldown and relatively short duration.
Light weapons (or energy pistols in this example for "sniper" playstyle) can now safely drop AGI and PER, have no STR requirement
So let me get this straight - you are dumping PER and STR on energy pistols, which means you are losing 22% crit chance by not taking Scrutinous and Steadfast Aim, but energy pistols have an easier time getting to 100% crit chance than sniper rifles do?
and with more levels and stat points with versatility specialization have the same or higher weapon skill
Yeah, no. You are not getting the same or higher guns skill of a build with 15-16 PER by using Versality. At level 30 with 16 PER, the effective guns skill is 323. At level 30 with 16 DEX and Versality with maxed spec (which is 10 out of your 15 points), you will have 258. That's 326% base damage vs. 281% and I dunno how much lost precision, but definitely not negligible. Even with 20 DEX you would be at 302 guns vs. 377 with 20 PER.
but with lower AP cost, higher damage from intelligence and 90-100% crit chance always
You are not getting lower AP cost with plasma pistols, you can with laser but then you are not getting anywhere near to 1-shoting everything. You are losing damage by going with Versality, then getting it back by picking High-Technicalities and pumping point into INT, in the end you are losing 2 feats, 10 spec points, who knows how many ability points into INT and not even getting your precision back. 90-100% crit chance always is a bold claim, let's see the math. I sure hope it doesn't involve being at less than 30% HP at all times.
Crossbows cant one-shot Tchort. They need 3-4 corrosive bolts. Big Fucking Deal.
I saw it done in 6, barely. I would love to see you do it in 3.
The one-shot Burrower Warriors, Azurdae Goliathus, Tchortling Devourers, Industrial Bots, etc.
I have a hard time believing you are reliably 1-shoting industrial bots with crossbows. I also have a hard time believing you are 1-shoting anything on that list before being at least level 20+, snipers on the other hand 1-shot everything they can see much, much sooner.
Enemies mechanical resistance does not mean much when your primary damage source is electrical and acid. Who would have easier time killing Magnar and his 20+ buddies?
But huge HP bars do matter. I'd say crossbows would have an easier time with Magnar since they excel at crowd control and dealing with squishies and the limited space puts snipers at a disadvantage. But they can still win that fight, no problem.
You do realize just how easy is that when you can kill 7+ robots per round? It is not really even worth mentioning, let alone bragging.
I think pure psi builds would really struggle to do that and they're considered to be among if not the most powerful builds overall. I can believe crossbows can do it with shock bolts. Just goes to show different builds excel at different fights.
Also i seriously doubt that naked kill was on dominating.
O ye, of little faith. Here, a version for cynics with the 3000 HP Tchort has on DOMINATING shown:
