Survival fun but not rewarding
I like the way survival was made you start with nothing but a pistol and you have to grind your way to the darkzone dealing with cold , food , water and of course infection.
A good survival game take about 40min to 1 hours and if you manage to kill some bosses and extract you can get arround 10-12 caches in my opinion its not enought.
Most of the time your not gonna be able to finish your survival game and if you manage to do so you dont have much time to farm bosses in the darkzone to realy make your time worth.
Right now were getting way more loot farming 1 hours in the DZ/ LZ vs survival
In my opinion you should get 1 survival cache for entering the darkzone and 1 survival cache if you killed 1 player or in PVE revived one player with medkit.
That way survival still can be a good source of loot without actualy wasting your time.
