Burst Precision: To me, this is a bit of an odd trait. It currently competes with Berserker’s Power which grants 15% additional damage on full burst. At a first glance, it seems like a full glass cannon warrior has absolutely no need for this trait. It definitely won’t be a trait used in PvE. In WvW, a full glass cannon warrior with fury already has kitten near 100% critical chance, if you use critical burst, it probably is 100% (correct me if I am wrong there). So it seems like even a full glass cannon warrior will find this trait completely useless and redundant. Why would they give up 15% damage?
The next thing one would think of intuitively is, what about wearing all Valk’s gear? If one can crit 100% on burst, why would you need precision?
This is an example of a classic zerker build except that it would utilize valk gear. Unfortunately you cannot take full advantage of valk gear because the trinkets only offer a hybrid. So with the Signet of Fury you would have around 30% crit chance with fury that makes it 50%. The choices in terms of gear would already make this build half redundant and suboptimal. However if you have Signet of Fury down the crit chance is only 21%.
However, you would have around 25.5K HP. With WvW bonuses that might push 28K. With Guard stacks you might be pushing 30K HP. Which truly is a lot of HP for a supposed glass cannon build. However, you are losing 15% damage from Berserker’s Power which is quite a lot. And the 100% critical chance bonus is only for burst skills. Which means with fury, you are only critting for half of your hits on average (which really isn’t a whole lot of DPS compared to the classic glass cannon which crits on at least 80% of their hits). So essentially it is a simple tradeoff of more survivability vs more overall sustained burst DPS and more damaging hits. However, with no toughness, mitigation or condition removal, having 30K HP doesn’t mean much if you get hit by 12K backstabs or laced with conditions. You just have a better window of absorbing 2 more big hits and maybe being able to sustain smaller hits for a few more seconds before you need to back off. Instead of Berserker gear, you could get cavalier gear, but you would be reducing your damage even further.
Another possible set up would be going 30/0/20/0/20 as a roamer build. The main weapon set up that would take advantage of this trait set up would be axe/shield + greatsword, since it is extremely important that eviscerate from the axe crits. Not so much for weapons like hammer, longbow, greatsword, sword, mace, etc. Now this theoretically wouldn’t be a terrible set up at all. You can still be quite tanky and do nice damage, except however it is suboptimal.
You lose 15% damage from berserker’s power. You should already have around 60-70% crit chance including fury if you have built for it. Which is plenty. for eviscerate to inherently crit most of the time you want it. If you intend to go full valks, and have around 40% crit chance with fury, relying on a burst to do all your damage for you and then having terrible DPS until your burst is up again is a dangerous ideology to follow. This is because you are not always going to land eviscerates when you want to, and even if you do, it may not be enough because you have low sustained DPS.
It would be a build something like this:
However, what makes this trait even more redundant is the new sigil of intelligence, which causes your next 3 attacks to critically hit. As a rifle build, you can easily switch to it and then immediately fire a killshot. Then stay on rifle for a bit, switch to your offset, wait till your rifle burst is back, switch, then fire killshot again, etc. Same thing for axe. You can land Bull’s Charge, switch from greatsword to axe, then eviscerate. Or if you are close enough, you can switch from greatsword to axe, shield bash then eviscerate.
So overall, a 100% chance to crit on burst isn’t as amazing as one may see it. Because most glass cannon builds already have close to 100% chance to crit in general. Not building precision to take advantage of this may seem like a good idea in theory but relying on burst for most of your damage is a dangerous path to take. You lose 15% damage from Berserker’s Power, and any attack that isn’t a Burst ability is only going to crit half the time on average at best as a glass cannon. As a roaming build, even less so. The sigil of intelligence basically addresses the need to crit on burst although it requires good timing on swap.
