a little backstory... Ok not long ago i finished the research on these, but i simply refuse to install them. I have light thetacron installed at the moment, and as a builder their upkeep is quite low. To upgrade would cost me around 160billion credits, close to 40k Kurenite, and would boost my upkeep (currently 1.6billion) by around 4 billion. and all for a measly 800 attack!

My suggestion, is to lower the cost of the top weapons, to at least scale reasonably with the slightly lower ranked ones. Instead of being almost 10X the price for a 25% upgrade over Light Thetacron.

Heavy quasis are made for high ranks that are nearing max upkeep anyway and want that last little bit of oompf in their attack. The problem is that too many people are "guns first" with their research. Which at low ranks is good, but by the time you get to quasis, your ship tech should be fully balanced. I see tons of people on my BT that have various stages of quasi cannons installed yet have only 4 hulls or 2 shields or "outdated" defense mods. Once you get to the midranks, it's all about balancing your ship. I've noticed that most of the people who complain about the cost of quasis are midrankers that shouldn't be looking at building them yet anyway.

You'll get to the point where none of this matters. When you get to that point, you install them.

There's not really any point at which you should bother installing them; by the time you can afford them they'll (hopefully) each give less than a day's worth of attack increase. Save your credits for planets and buying useful artifacts when you can.

So you either can't afford them or don't really need them?
Sheesh, I'll just stick with thetacrons (except the quasi-chaos minefields)

It's all perspective I guess. Personally if i can afford them (meaning save up to buy them, pay the upkeep, and still be able to afford colonizing new planets) then I see no reason not to get them. They may be less than a days increase to some, but that's still a weeks increase you didn't have before installing them.

Colonizing planets gets pretty expensive, that's why the cost is never worth it.

At the point it gets to be too much, the costs to colonize a planet are far beyond the additional upkeep of a quasi. Meaning adding quasis would only add a few hours to a day to the time needed to build up the credits for a planet, which to me, is an acceptable tradeoff if you aren't trying to take tons of planets at once. And since I'm growing increasingly picky in what I take, I suspect that I will hold out for the best planets I could find, and a couple hours won't matter anyway.

Again, just a matter of perspective.

Well if all else fails you can use GP to abandon your crappiest planets. It's slow but effective.

This is where I am; credits are no issue. You can never have enough attack.

ive finished planet structure research, scanner research, shield research, hull research, and weapon research. got all my best hulls in. 1 scanner, 1 shield (limited by size), and im rank 383. 3735 attack 4446 defense, 11800 hull 2800 shield.

What's that in reference to? Seems off topic unless I'm missing something.

Here's my understanding: I don't have QCBs but from what I've seen here and other threads they are extremely costly for such a small amount of attack that could be fixed with a bunch of prisoners and rank ups. Those extra creds could be used for other things like one day beating Mento in a bid for a dyson
Most stats on your ship can be replaced by rank points, QCBs are like a shortcut but the shortcut doesn't really go far once you can actually afford them.

just aimed at darth, showing im not exactly unbalanced in my ship.

True, to an extent. This is also true if you take it to its maximum logical conclusion, being don't install anything that can be created through artifacts, because credits are more important. Meaning no attack, no defense, no hull, and no shield. While clearly this is an exaggeration to prove my point, the fact is that credits can only get you so far with a ship valuing the "intangible" of wealth over the combat ability of the ship itself. Everyone has to develop their own line as to when credits are more valuable than a certain boost you would gain from the modules. And while QCB are admittedly very expensive, for a disproportionate bonus to attack, for many end game players the boost is still worth it. Just depends on where you personally draw the line.

Yeah, also the deck space that would've been used for it won't exist, lowering your damage cap... I think...
Meh, to each his own. I'll only do the tier for the minefields.

You are nowhere near ready to install heavy quasis. You would have been better served researching cloak to hide your best planets and Base tech so you could contribute and use your legion's UST (assuming there is one). Keep in mind that just because you might have something researched, you don't absolutely have to install that tech right away. I had other stuff (primarily base tech) researched before I finished Quasi tech. I did the minefield then stopped. Completely finished it around 525. Didn't finish installing all eight until nearly 700. You should have your defense and hull fully maxed well before even thinking about installing quasis. And always live within your means. If you can't afford it, don't buy it.

Also true to an extent lol, the QCB are the most efficient of the research-able weapons, so while it would raise damage cap, it would also be a more efficient boost to attack. But as you said, to each their own. Just using this chance to provide as much info as possible to the poster.

I guess it also depends on how much your Legion relies on you for the Base upkeep. I've essentially had to deal with both ship and most of the Base upkeep, so that makes a big difference in how much you can afford.

maybe they should scale building costs and upkeep with your rank....like for a rank 100 thetas should cost 250mil+200ku; rank 200=x2 of rank 100 and so on
upkeep should be like 1mil*rank
