What's your opinions on 2b2t?

2b2t is only really entertaining to play on if you actually go on with a plan. Otherwise your usually gonna sit in queue for 8 hours until you finally get in, establish a base and then get griefed while your offline; rinse and repeat.

If your willing to deal with those aspects though then I'd say it's alright, however you'll be dealing with lag and traveling the nether highways for a while before you get far enough away that you don't get discovered by accident.
