I don't see the problem here. Doesn't this mean that points A and C are open to take? And please don't call this a cheese, as unfortunate as it is, four titan bubbles piled onto one another is a legitimate strategy, one that comes with its drawbacks. A well timed Bladedancer could cut through most of those Titans before dying. Now, wether you decide to keep going back to feed them kills or move onto another point depends on how stubborn you are.
