The Powersword feels like the ultimate weapon. Sure it does slightly less damage than a revved chainsword, but you get two swings each charge and don’t have to deal with the saw time. The charge even glides through for super-damage against groups. It’s not like you give anything up for the regular attacks either, the swing patterns are great and keep good armour damage.
It’s not that Power Sword is overtuned. Imo it’s in great place especially if you play on Diff 4-5. It’s the only weapon for Vet that is great to fight vs mixed hordes where you have armor and trash mixed. The only other weapon as good as that is Eviscerator and that is also cool.
The problem is that all other weapons are bad. The are way too low amount of weapons that combine both good cleave and anti-armor damage and those are the weapons you want to take on Diff 4-5. PS is the only option for Veteran for it.
Tons of other weapons sadly are only good against trash and deal no damage vs elites/super-armor and specials.
Currently Eviscerator, Power Sword, Dueling Sword for Psyker and shield+mace are the best weapons to run on Diff 4-5 becasue other weapons simply are not good enough.
It was the same in V2. On highest Diff the weapons you take are those that do both good armor and have good cleave patterns. Mace and Sword, Sword and Dagger, Flaming Sword etc.
While I understand the “powerup for balance” its not canon pr se, We should have at least 3 swings pr chargeup, as it is theres way too big gaps in your defence powering up every 2 swing.
