I also played offline mode. Because no one here could give me advice for the barroth, barioth & rathalos offline arena, I decided to try something different. I tried the rathian & rathalos arena quest. This one gave me at least a hammer to fight. It's not my favourite weapon, but I can use it a little bit. Of course I lost at the first try, but I was able to take down rathian. I ran out of potions, so I thought I should use a little trick. I started a two player match and used the players alternatively. So I had the double amount of items. And I really managed to take both down and finally got my first rathalos coin. I did it three more times and now I have an outfit with the skill Carving Master.
Using the hammer was also a nice experience. It's fun to hit a wyvern with a hammer on the head. Maybe someday I will be skilled enough to kill rathian & rathalos with just one player.
I still hope someone can give me hints for the barroth, barioth & rathalos offline arena. The offered weapons are not really my prefered weapons. I have not enough skill with the GS. And I have no experience with the SA, Lance or bowgun. And barioth is one of the monsters, which gives me a few problems. His high initial speed and crazy attack pattern are reasons, why he would be much higher on my list than on Mr Khans.
