For all the folks who keep whining about the WB only beating a tac squad by a small margin, I'll say it again, using bold letters, only for the sake of being constructive, so they don't bring this up again, no offense intented:
The WB initially costs nothing for you, compared to a tac squad which costs more than a whole power farm and occupies the HQ build queue. You kill an 500 req squad with a free hero. Isn't that enough?
I hope I made this clear.
Unless your opponent has at least 3 tac squads, they're slow to respond to threats and can be outmanuevered, outcapped, and outsquadded. Don't just try to kill them, try to win instead.
