I mean, the greatest Forsaken battle was Lanfears' IMHO, and she literally just started walking towards Rand and a wagon killing everyone and everything around her with no real strategy planned out aside from her general preference of attacking from the flanks and using Shadowspawn to occupy Rands' forces in the front.

I understand that these are our heroes, but this string of "bad luck" really trivializes their threat and makes them seem like a cast of Disney villains, so I'd rather just say they are stupid and their anachronistic behavior is what is killing them. After all, technically speaking, the Age of Legends, as wonderful as it was with technology and etc, was less evolved than the current breed of humans in the 3rd Age.
