It's not point A that's the problem. It's the placement of B and C. You can have 1-2 guys protect B from the old B spot and cover one entrance, while the rest sit near the heavy ammo spawn covering the other entrance. If someone pushes C, two guys run out and prevent a turn the run right back in to cover B. So the only plan that makes sense for Alpha team is to run a guy at B, while the other five push C hard and attempt to cause a spawn flip. I've performed this sudden flip many times and have started shooting dudes on my team if I see them run for an A cap. Pure defense of B and C is the best plan on Blind Watch and that's why the spawns need to change.
