1) the new default client looks very nice now.
2) It still lacks the essential things: item radar and free camera movement. If you can not include those things till f2p launch you should use enders client as default client.
3) It took me about 20 minutes to find something to craft an inspirational near Jamestown. You will lose 90% of all f2p on this point. This needs to be changed.
4) tutorial still remains unclear in some points. F.e. "learn childish things", "put some clothes on" includes no explanation. How about "put some clothes on by opening the equipment window and drag and drop the item you want to equip from your inventar to the equipment slot..." or something like that (with better english). F2p players are used to be treated as if they would be the silliest people on the world.
