First thoughts...
Everyone spawning in the same few areas means that most building spots are already taken - especially problematic for the players starting later who are more likely to be ones who haven't played in previous tests - the people least familiar with the game are the ones who have to trek the furthest looking for a spot to claim (or even for un-looted trees to get some branches from)
Then they get the joy of building a house... if you want us to test particular aspects of the game don't make us go through 2 hours of soul-destroyingly tedious house building. Unless house-building is one of the key things to be tested, it should (during testing) be a lot simpler / quicker / easier.
Once I was half way through building the house walls I noticed a comment from someone in chat about how useful carts are - so I broke off from collecting logs to build walls to collecting logs to build a cart. 8 logs later it was indeed useful, I pulled it over to a tree, chopped the tree down, and loaded all the logs into the cart - excellent! Except it seems that while there was enough space for me to pull up to a fullgrown tree and let go of the cart, the cart was now too close to the tree stump to start pulling it again
