This is a big flaw in WvWvW. Single players are dead body scouting actions of the zerg team, so basically you have to trick 1 guy while moving in a zerg group just to not get confronted by enemy team who knows your plans and where you are heading thanks to that 1 dead man scout.
This can be simply solved by on death timer counting let’s say from 1 minute down, if noone picks you up during this time you get ported automatically to nearest wp. If someone touches you (not necesarily revives you) counter gets reset. Please think about it, atm it gives a big advantage to the team that lost the fight.
