Because the NPC's are having way more fun than me. God armour, God damage, unlimited ammo and grenades.
And they athletic parkour abilities.
And shooting through walls. Man what a great life they have
They can throw grenades with pinpoint accuracy and a mini-gun can shred your armor from 300m. Ridiculous.
But most importantly they get Helicopters to move around the map, and we have to walk.
You could use them as starting classes.
Oh and cool downs what cool downs, no worries for that.
