The problem with the Bash cancel into Guard Break is they can cancel in response to the dodge, and you end up eating the Guard Break every time, because your still in dodge animation when the guard break hits, leaving you no chance to counter.
Any move in this game without a counter is a bad idea.
Yes you could counter with a light attack but that only works for Heroes with a fast light. But if the warden is in your face the bash will hit before the light, so your still screwed.
