Thats 200 fuel, using 200 fuel to counter 400 MP + 60 muni + ..... and so on is absurd.
I hopy you are just trolling but if you don't I'm going to explain you.
Yes, 200 fuel to erase cheaper unit in few seconds. Not to counter. You can counter it in a lot cheaper way but it will take take to kill it, but for 200fuel you can erase it in seconds.
Calliope needs 4 barrages to kill Schwerer. That's 560fuel to kill Schwerer! Absurd, right?
Sure, you can kill it a lot cheaper but if you want to kill it in 3-4 seconds, then you need 560fuel.
