Even with faction resources unless you have one guy repairing the 100+ guns in base 24/7 you just have a huge stockpile of worthless crap.
And this is how it suppose to be ! If tehre was no detoration we all would have an army arsenals.
Repairing guns and armor monotonously is not fun.
I think problem is not with the deterioration i never got item for long enough to have it totaly broken i got killed by pk before that. but it would be nice to have npcs that deal full damage not dropping 90% det useless weapons
If you want to make enemies, try to change something.
