I dislike the 1-piece catapult arm. It's completely useless for anything but catapults, and maybe scooping ice cream.
I think those thick round brown parts make poor wheels, but I like the part in general. They can make a good tree trunk.
The figure is nice, but it does get redundant when half of your minifig population is wearing an eyepatch. Wolfpack had that problem too.
Most of the parts in the set, aside from the ice cream scooper, look like they are useful. If I was not in my Dark Age while this set was available, I would have bought a couple if TLG priced it well.
As usual, I'm not going to make up some arbitrary number rating for this set, but let's assume I would rate
6030 Catapult around 8. This bull catapult would rate lower than that.
