I think right now you don’t get enough Quests, the Quest’s are kinda boring and the rewards are disappointing.
Already made a post about that too.
If my suggestions are to specific, you might prefer this idear:
Behead 40 enemies with a sword.
Kill 5 Gas rats with a headshot.
Make 300 Boss damage with melee.
Kill 8 CW’s.
Kill 5 Berserkers with melee
Make 2500 damage with pistols.
Make 30 bomb kills.
Kill 30 enemies with barrels.
