Could the spawns on Dispatch suck less?

Playing that map is suffering because the attackers have such a clear line to the defender spawns, meaning a well coordinated team with a warthog is all it really takes to make losing the garage a foregone conclusion. I attribute this problem to the spawns. Any way to make them less terrible?

Here> Put an “armory barrior” over the tunnel till armory is captured.

And for fairness blue would get more rocks at their spawn.
