What is better, using them on Heavy Thetas or Heavy Quasis? Now i know u all will say whatever u want to use them on, but i'd like to hear from others what they would use them on.

U max out a heavy Theta u get 716 attack per cannon, with an upkeep of 520mil...If u max out a Heavy Quasis u get 860 attack per cannon, but have an upkeep of 2.05bil..The difference in attack goes to Heavy Quasis as the attack between the 2 would be 1152, But upkeep wise goes to the Theta's with a difference in upkeep per cannon being 1.53bil. Now each day u save with all heavy thetas is 12.24bil.

What do y'all think?

I think using them on Heavy Quasis is absolute end game content. When you are at the point where you are so picky with what you are colonizing credits isn't an issue, you will want to have your upgraded Quasis.

Personally speaking, I wouldn't want to do the mission enough times to fully upgrade my thetas, then look back later and be faced with doing it all over again if I want the top guns. Of course, depending on where you are in the game atm you may choose to upgrade your thetas for the immediate boost and just count on time running its course while you build up the upgrades again for Quasis down the road.

EDIT: Edited to fix typos

I will use them on Quasis.

I'd not use them until you have 5 in cargo. Then sell everything and install 1 quasi. Use the 5 havoc coils and reinstall the other 7 cannons as heavy thetas or nulls.

Repeat every 5 coils, which should be every month or so. That way you'll ease into the greater upkeep.

On average, you'd only get 1 or 2 Coils each month, as there are 8 Legion missions to go through.
