Sniping
-Headshot-
3/5
Pretty much every build will go for Bore and as the option for this skill is Optics, which is completely useless, this is an automatic pick-up. In that sense it might as well be marked as 5/5.
3/5 fun. It’s just a crit boost.
-Optics-
1/5
Terrible for anyone. One of the worst skills in the game. The aim stability is not very noticable because the shake effect is not too bad in BL2 at all. The zoom boost ranges from whatever to outright harmful, if you are trying to fight enemies close-up but would still like to ADS.
X/5 fun. Don’t pick it. If you do the fun is subjective to how much zoom you you want for whatever scopes you are using.
-Killer-
4/5
Kill skill for good crit and reload boosts. Another automatic pick-up. The bonuses are large so this is a really good skill while mobbing.
4/5 fun. Mobbing with effective kill skills is always fun and Killer is a very good one.
-Precicion-
3/5
The way accuracy works in BL2 makes this skill slightly underwhelming, especially since it’s not a huge boost per skill point. It is very good for shotguns (5/5). It can benefit pistols, AR’s and SMG’s to tighten their spread so might consider throwing some points here. Not a priority though.
5/5 fun for shotguns, not so much others. EDIT: This skill as well as Velocity is boosted by Legendary Sniper COM so shotgun users generally gravitate towards that. The COM also boosts OSOK which is generally something shotgun users like.
-One shot, one kill-
4/5
Very gun specific. Low mag Jacobs shotguns? 5/5 rating. Vladof pistols? 1/5 rating. Best benefits shotguns and snipers, as they have high base damage to capitalize on it, and builds focused on those do max out this skill. Others usually leave it alone or at best use it as a dump for extra points for a small DPS boost.
5/5 fun for low mag shotguns or sniping gameplay where you intentionally reload a lot. Synergizes really well with Killer and Followthrough for that kind of one shot gameplay. At OP8 you’ll likely need more shots but still very fun.
-Velocity-
3/5
Very controversial skill. On paper it’s really good but in practice the way bullet speed works is often screwing with a lot of guns red text effects. You most likely want to max it out on builds focused on any guns that don’t get negatively affected by bullet speed effects.
4/5 fun for anything benefitting of it.
-Bore-
5/5
Good ol’ Bore. I’m not going to explain how it works. It’s been done so many times by now with even pictures included that there’s no point for me to get into that.
Almost every build wants to pick it up because it can be used to one shot the double Saturns at Digi Peak. Outside of that it can also be used to one shot UBA Constructors, the Bunker and it can one shot a single Saturn but usually just does a ton of damage. Occasionally it can oneshot a couple of regular enemies whose hitboxes are lodged into each other.
In everyday gameplay the skill is 3/5, maybe even a 2/5. It’s nice extra DPS here and there but it’s kind of rare to get anything spectacular out of it while mobbing. It does have synergy with Execute as that causes knockback on the enemy you are hitting so you can occasionally set up a Bore chain with it.
Very fun when it works.
-Kill confirmed-
2/5
A somewhat problematic skill. Not completely useless but the requirement for getting benefits out of it just doesn’t happen in practical gameplay as it gains stacks so slowly. It best benefits SMG, AR’s and some pistols so if you are a general gun user it’s ok.
Snipers (and shotgun users using sniper COM) can sneak a point or 3 in it as it occasionally kicks in a stack or even 2 and the sniper COM boosts it. You might get 1-2 stacks when going for shots out of Deception too.
Note: trying to actively play around with this skill is in direct conflict with building CA stacks and is also wasting time out of your kill skill bonuses from Killer and Followthrough.
1/5 fun. It’s just not a skill you want to play around with because of how it works. Lining up a max stack opening shot is the only situation where you should see full stacks and I don’t know anyone that bothers staying still that long
As a matter of fact you’ll have more fun with the skill if you don’t actively try to benefit from it.
-At one with the gun-
5/5 (for Snipers)
Non-snipers have no reason to pick this. The extra reload is very good. Extra mag size is obviously nice so you don’t have to reload as often. The hip aim bonus can be surprisingly beneficial (sniper ADS is pinpoint accuracy always anyway). It’s pretty much an automatic pick-up if you are going for CA below.
4/5 fun. Good bonuses for snipers. EDIT: I raised the fun from 3 to 4 because having 5 more bullets before forced reload is a big deal that was hard to value before trying without it.
-Critical ascension-
X/5
It’s kind of impossible to give a rating for CA. On the other hand with some snipers in some areas you can absolutely demolish everyone with it. On the other hand some snipers get nothing out of it. Area also affects its usefulness as some places in the game simply won’t allow stacking.
Anything between 1/5 and 5/5 depending on area and weapon choises.
The fun factor of this skill is directly tied to how effective it is so use the above for reference.
