I kind of like that since I know where the goblin is so I can grab a quick health pot or a knife, but it is a bug nontheless.

Would be funny to have an invincible pet (possibly a small pig) that follows you and collects any coins nearby.

I'm not so sure about a wall in the middle of the arena, especially since you get damage if you hit it. Maybe just clear all weapons when the match starts and make sure they're in the player's hand?

I like the certain / random weapons.

I see it too sometimes for different helmets/weapons. It's just for a split second though so I haven't mentioned anything, but it is something that can be distracting.

Would be fun to conduct group fights, but the same could be done through training mode no?

Possibly, but would grinders appreciate having refreshes every month? I just don't see why it has to be done.

It's casual gameplay, I don't see why you have to make it ultra competitive. If players want ranked fighting, then they can go to the arena.

-5 seems like a lot. I think -2 would work better.

True, but I wonder how much the game would change. I have just started getting used to the new mechanics, and while I still don't like them 100%, it would be a dissapointment if it was to change drsatically again.
