Remove pepperspray or make it even more rare, why give PC like 5 extra peppersprays at some point lmao
Nerf animal tf/punch punch kick kick
Nerf science skill giving absurdly high pain tolerance to PC
Nerf eng skill somehow also being a dmg source in fights
Nerf animal tf providing godly smh through cow (headbutt) and/or cat/wolf tf (bite)
And then to keep things interesting introduce certain NPCs having gimmicks that the PC has to watch out for.
Biggest issue is generally the wonky scaling that makes PC a god mid to lategame though.
