AV Horde wall climbing

Hi,
I guess I´ll get plenty of hate for this but should really the wall climbing be allowed due to the advantage it gives their faction in the BG? Pretty much backdooring and avoiding all NPCs guarding our keep etc.

This is a open question for discussion since it´s getting kinda tiresome having hordes capping Aid Station after 10 min zerging in with 7-10 players. Since we as alliance have a easier time avoiding horde choke points maybe these to takes each other out?
In my last AV we were about 6 Alliances defending and we barely made it defending against 9-10 hordes.
Ah well. Discuss.
