I can see no compelling reason to use a Federation Wolf class frigate hull over the Federation Gazelle. Its just inferior in all stats except for one, and that one is a very very small difference, that if you were to design to exploit it, you would go for a different hull. It really should sport 5 hardpoints or 8 standard modules, or stronger bonuses. Something to actually give it a reason to pick that hull.
Likewise, I see no compelling reason to use a Cruiser Quantum Blaster. I dont know if I am missing something about it. It does less than 1/5th the dps of a cruiser laser, its closest competitor. The only advantage of having low power and a lower cost on a per item basis really fails when compared to the dps/cost or a dps/energy comparison. I would love to see it get re-tuned or re-purposed.
I forget which rebel frigate is unlocked. the 4/4, 4/7 or 6/4. They all have their uses. I primary use the Loki (4/4) for a cheap fast frigate. It has the smallest non fighter hull in the game. Anything that has the “X most” in this game can be used as a best of type for a strategy. Small means more of them can crowd around other ships/baddies, and I suspect is harder to hit. I only put 2 weapons on it through. I use the 4/7 for my anti fighter hull. It needs to be tougher because the fighters tend to retaliate against it. And I have a great 6 torpedo design for the 6/4, although it is slow.
But the Wolf class frigate is literally the gazelle with worse stats. Its larger, matches the hardpoints/standard module count, costs more, has the same bonuses in lesser amounts, all for 1 more power. The power on a frigate hull only really matter to all missile + armor boats that have no power core. But if you wanted more power, you could pick a different fed hull that has even more power on it.
dps is not the end-all be-all of a weapon. The tracking speed is critical to being able to hit what you’re aiming at. If your play strategy is cruisers vs. cruisers with fighters / frigates to take care of enemy fighters / frigates, then tracking speed is largely irrelevant (cruisers are floating pigs waiting to be slapped with damage). My take on the Q blaster is that it is an anti-frigate weapon for cruisers. Since I prefer to kill frigates with rocket fighters, I also don’t actually use the Q blaster. But I don’t know that I’d take it out of the game or repurpose it, I think some players would rather deploy an all-cruiser all-the-time fleet and for them, this kind of weapon becomes relevant.
If the difference between 1.1 and .9 tracking speed actually gave it 300% more dps in that situation, I would agree with you. (not 400% because the quantum blaster is cheaper). But currently a fusion beam, as it has a 1.5 speed, or a Cruiser Pulse Laser, as it has 2.6 tracking speed while still having enough shield pen to break any frigate, would be a better choice for the role you described.
