So as I've been trying to record numbers for Wintergrasp I've begun noticing a trend. Simple, deadly trend. It goes something like this:
When we attack in two places, we win.
When we try to keep forcing through one path to the keep, we lose.
I think that there's a certain merit in the One Path, One Win mentality, in that it groups up your force for maximum effort in the smallest space. I think it's also worth considering that WG changed a while back with the addition of the southern towers actually meaning something, and that the corresponding point to our maximum effort in one spot, is that it makes it really easy for the horde to figure out where to put *their* maximum effort. Almost every offensive game I've been in recently, even the ones we won, resulted in the loss of our southern towers, to the point where I think you can almost say that it's axiomatic that you have 20 minutes, not 30, to capture the keep. And whereas before you could overcome horde defenses by hard-pushing through two walls and getting to the keep, I am not sure that that remains a viable alternative. Time favors the defense.
But if you mount a secondary attack, even if that's only a diversion, you force the horde to split their defenses -- and if you THEN mount a concerted effort on one side, you may be able to break through before they can switch people back over off the diversionary side.
It's interesting that that seems to be at such a complete contradiction to strand of the ancients, the BG most like WG, where you *do* want to mass everyone at one place. I think that may be b/c the map is smaller on SOTA, and so it's easier for the defense to switch from one side to the next and cover a split-attack. I find that a good way to win strand against a split attack is to pile your defense on one side and wipe out the tanks there; you'll lose the other front-gate, but with only two tanks (and damaged ones at that) you can regroup and stop them at the second gate (or lolth forbid, the yellow gate) and the loss of momentum is often irretrievable.
