I know there are a ton of posts about claims, but wanted to add something else. I agree with all the others and a limit of 1 per person is good to start. To help the solo players have a bit more land mass put additional claims available under the skill trees so that you can go a good depth into a skill to get a 2nd. And maybe even into one of the other trees to add a 3rd claim. But no more than 3. It is crazy how huge islands are completely owned by a small group of people...
