With the change from striking first on the charge to I1 (greatsword) + 3 on the charge, counter charging with greatswords isn't a hugely great option - do it to elves and you might end up all dead before you get to swing.
Against Elves I guess anyone with low I is taking it to the chin. And often has, in other editions too. Striking first is an Elven feat, part of the spirit of those armies.
So the comparison here isn't that informative. Against many other armies, a Greatsword (counter)charge will work still.
Also, charging a flank should reduce Elven attacks from spears, which are a common Elvish choice, but which only work to the front. (Unless this ed changed that.)
