The Charge isn’t random on it actually. It is based on mass, thus the reason why you only get one or two swings with it against a Crusher but easily 4 against Poxwalkers, unless there is too many of them which causes the charge to run out faster.
It really wasn’t, much like the Boltgun, people outright ignore the glaring issues with the weapon that can lead to your doom UNLESS you have teammates that do their job.
Sure, the thing does incredible damage partially due to how burning works right now, it can also stagger and can delete a horde coming in.
Now I would like to see how well this weapon does against a wide open room full of Gunners and Shooters spread around the room, alone, without the help of the other teammates. Suddenly that gun isn’t OP, is it?
As a Vet main, the Power Sword had exactly 0 downsides to it, making the class as a result have zero downsides to it. If you approach the class from the perspective of understanding the basic mechanics of the game, AKA, Blocking, Dodging, Cover, Suppression and Weakpoints, you will very quickly realise, the PS made the Veteran practically invulnerable.
Their ability allows them to ignore suppression, making them able to nuke down any Gunners and Shooters aiming for them, including Reapers, the Power Sword prior to nerf, could simply be activated with a 3 frame animation and then do 3 swings into a horde to do the same amount of damage as the Zealot could do with the Flamer, though obviously in melee, while also offering perfect counter against Crushers, Maulers and Ragers. They also have access to the Frags, which also serves as an excellent horde clear and CC as it knocks down Crushers, Bulwarks and Reapers even.
The difference between the PS and the Flamer is significant. A Flamer has a glaring downside to it as a weapon for the Zealot. I never take mine when I play with Pubs for that reason. So many ignorant or outright inexperienced players forget just how strong the Shooters and Gunners are as many of them are still under the mindset of Darktide = Vermintide 3, and as such don’t realise that Darktide is a shooter first, melee game second. Flamer has range disadvantage, it does not help you deal with targets sitting across the zone from you. It doesn’t save you from the Sniper taking an aim at you from the opposite end of the Trainyard, and if you are flaming with that thing, unless you can react on a flash, the sound cue for the Sniper Shot before impact is only 2 or so frames, meaning you need to press dodge the moment you hear it, any less and you are hit, unless you see the laser through the flame effect.
To summarise. The argument between the PS and the Flamer being even remotely similar issues is staggeringly wrong. The Flamer has a downside to it, the Power Sword didn’t, and this resulted in the single best all-round class in the game capable of fighting off all threats they came across while the Zealot could only ever deal with close range targets should they choose to Flamer, making them heavily reliant on their teammates for survival.
