I have a content suggestion regarding comabt.

There are certain enemies (****roach, King Dozer, Axl, etc..) that have no weaknesses. This makes fighting this enemies feel less like a challenge and more time consuming then anything. Its one thing to avoid resistances, but having to build around weaknesses is significantly more fun than just chunking an enemy with a random weapon not in the resistances tab.

It just in general makes the combat more involved and makes fighting bosses such as Axl and King Dozer feel more interesting when they have weaknesses. It could even be an element or damage type that is particulalry difficult to obtain; being able to destroy a boss after lots of work practicing / collecting the right weapons is very fun.

AXL has a weakness and it is stun. His mechanic revolves arount being able to stun him and you can shorten the time spent on AXL dramatically if you stack up stun damage / 2h club.

I second OPs suggestion. The bosses are fine so far and even better mechanically than the bosses of Grounded 1.
