I’ve played about 70 games of warzone since launch, but seldom does a match end up with my team having to defend the core. But i’ve noticed ever map for warzone has the same sweet spot for hitting the core from outside the base. Which makes trying to defend almost impossible when the other team just sends tater troops in to distract while one or two sit outside in a vehicles and can hit the core at a certain angle. This shouldn’t be possible, if anything for quick fixes place a barrier infront to block the LoS or relocate/move the core back some.
Good find, core should definitely not be hit from outside the base.
