I know I'm basically hating on him on everything he's done, but I can't help it.
First off, the map on Pirates VS Tribesmen is completely default. All chappers has done is just add classes, random props and duplicated the ship and islands closer (used the Pirate DM build).
The places where he's put the classes is horrible, I won't explain it, just join the server to find out.
There's a medic class that has 2 weapons (what? why not just one underpowered? The medic would be OP with 2 weapons.) and a syringe that the medic can only use once, which basically then makes the medic not a medic anymore.
There's horses that are slower then some classes, as some classes have poor weapons but are pretty fast. Doesn't this make the horse useless?
One thing I like is the daycycle he added in, it's balanced because lights were placed so you could see in day and night.
