It's a gamble. It only works if you can force a mass retreat with an inferior army.
If your opponent spends the same amount of munitions on his own abilities and weapons you're especially going to be behind. (Most players float like crazy though.) He'll have brens, bars or ppsh. He'll have medium tanks, artillery and likely more map control.
I could see it being more of a problem in scrub vs scrub (4v4) but in a real game mode I just don't think it's a big deal because you're trading army value for the opportunity to nuke him in the late game if he retreats everything together.
Okay, look, I tried playing nice with you, but the more you post the less I think you know what you're talking about. I mean, remember when you thought the SU-76 and the t-70 had the same gun, for God's sakes? Can you play a bit more vs. them before going off and defending it? Your post shows an immense lack of understanding of RTS and is not how this game works at all. Just like with that SU-76 fiasco.
You can easily defeat someone with an army that is under value vs. theirs. That's what a "counter" is. It's when a unit with less resources beats another unit with higher resources, putting you at an advantage. The commander lets you spam LMG grens. That holds off infantry. You can get 2-3 AT guns since you're not spending fuel so you don't have to tech up. That holds off tanks. No matter the unit comp, this will always either beat or hold them off while using less resources. Stall until 12 CP. Then do it.
And who cares if that strike doesn't win the game? I'll reiterate since you refuse to go back and read posts that already excuse yours: As long as it's uncounterable, it's cancerous to gameplay. Even if you can't do it every game. Even if you don't wipe their army every time. As long as you can do it SOME games, while wiping ANYTHING, as long as there is no counter, then it is cancerous. Get it?
In fact, why are you even defending it? My only suggestion is for it to not fire in the base sector. That's too much for you, right? Then go make a thread asking for all offmaps to be fired in the base. You can't do it because the playerbase is too casual? Then how about conceding this one, too? At least until you know how the game works better?
