Breach Defense & Melee Builds

Something seriously needs to be done about the way the defense and in particular fortress defense mechanic works - not everyone plays a class that can 360 shoot down hallways and oneshot the corridors.
More "proximity-dps" based coverage builds are struggling to defend the Fortress (and in some cases also the mini event in maps) as any splash damage even when u just sit on top of the npc will slowly make the hp bar vanish.
Even if AOE from these mobs was out of the equation; the amount of travelling that needs to be done to start dpsing before they can reach her will be physically impossible.

For now I will not engage with this mechanic till i maybe get so much coverage to even consider doing it as of now im getting kicked out of the fortress without any rewards whatsoever so I wont bother entering them anymore.
