You guys seriously trying to argue math here? Viper IV is really worse in every possible way than Vulture for pure combat period.
Just check numbers (both ships fully combat with stacked SB/HRP/MRPs with Bi-Weaves and fully engineered):
- C4 thrusters vs. C5. In similar build highlighted above, sheer speed difference will be ~50m/s and boost is whooping ~150 m/s. No surprise, since higher class can handle extra weight much better that lower one. You cannot really be talking about manueverability advantage here, which such jarring difference. And again, Viper IV doesn't exactly have small or slim profile like Eagle does, f.e.
- C3 distributor vs. C5, which lets Vulture have extreme sustain fire capability for only x2 C3 hardpoints, while Viper will struggle. This transfers to possibility of over 750 DPS easily for Vulture, with crippling experimentals and you won't have to put more than 1 PIP in Weapons with that. Vipers cannot even remotely reach these numbers, no matter how you outfit them. More ammo and more damage, what's there to argue?
- Then we take hull. Fully stacked for combat, Vulture will have about ~500 hull points advantage, but that doesn't mean jack since it wins in each resist about 2000 point!
- Then let's take shield. Vulture isn't only has over 300 more raw MJ, but easy gets +1000 more points than Viper in each resist. No surprise, since we're talking only 2 Utilities vs. 4! And biggest advantage here is that Vulture will have exact same Recovery time, but about ~20 sec more Recharge. That not to mention it can go Shield Tank with Prismatics + C5 SCB while Viper IV won't have near as much module capacity for it to be in any way efficient.
Arguing marginal maneuverability at certain speed threshold feels like a joke, when it loses in speed that hard under the weight. Raw damage is the ONLY thing that matters in PVE. In PVP nobody will ever take Viper seriously, it cannot harm any G5 combat Medium ship no matter how it's build.
I mean, you can do whatever you want with ship you like, but it doesn't make this ship even remotely good for certain purposes no matter what you do with it. Some players use Dolphins or Type 9s for combat, you can do that, but you will be very limited in activities you take part in, and there are plenty of ships that do that FAR better. Ships in ED are absolutely unbalanced and have very sophisticated roles. It's obvious as a day, I don't understand how can there be an argument about it...
