Yes. They have to come to you eventually… that was the entire point of Goats. You can out range them all you want, but eventually Goats would get to the point and then you have to drop and contest them.
Ps Rein moves faster now shielding then he did during Goats(post Lucio speed nerf). You can approach under Rein shield, then take cover for a few seconds to let it recharge. You don’t have to run directly from spawn to point.
You are not going to knock a coordinated brawl team off point without Ults or coming down to contest without giving them a tick.
