I find builders strangely more capable than an archer... I must really not care for the grapple, and the still incredible prevalence of the multi shot. Even if their walls are useless, they can still counter-mine, and build really annoying production lines... they seem to only be capable at very offensive/rush building. Also, going back to whatever I failed to say... Even if you have a more reliable wall run ability, does it completely prevent the possibility of a knight doing the wall-humping-shield-glide thing that makes the climb up walls infinitely.
