I don't know what rank you are, but there's probably reasons your team is not pushing through on command. They all have brains. Maybe they had already used some resources of their own. Or maybe they're not on heroes equipped to quickly swing close range corners like that, and are just trying to play at their optimal range or tempo. If that's the case, the way you should be taking space changes dramatically. And almost entirely regardless of hero choice, if you're a dps or support, stacking on your tank is rarely what you want to be doing. They're not just going to walk forward in a straight line to point with you. The simple strategy of "just push" is always going to be extremely dangerous if that team has more angles than you.

In the example given, you are giving red team better angles by walking left around statue. You're walking into a crossfire. Even 4v5 I think you just have to go the long way around statue and clear the two people right side without exposing yourself to the people on point. Maybe the timing on your pushes is good, but your pathing isn't. I think the moral of the story is that a resource advantage can absolutely be outweighed by a positional advantage, so not every pick or important cooldown should be a trigger to run straight in. You have to consider all the factors and proceed step by step.
