Well, as Bikerr already said: Refilling is allowed.
Considering there is no written rule yet we will add it as soon as possible.
You should always keep in mind that you will respawn with armour when dying.
Both options (refilling and dying) temporary remove a player from the turf.
refilling is only worth if you are able to complete it in a shorter time than it would take you from the spawn to the turf.
The first thing to consider into your strategic thoughts is that in contrast to normal clan wars the victory is here not at all dependent on the number of deaths, but only on the number of alive members inside the turf.
