I wanted to provide a better answer because a) I had some free time and b) I realized its two years after the original post, haha. I checked liquipedia to see if I could find some battle cruiser builds or info and I really couldn't. I played some online games and tried to rush battlecruiser (keep in mind I am a low gold ZERG player) and I found that Battlecruisers are useful if you get them in TvT against some lowlevel players. They're really good if you rush them out (get a trio before the 10 minute mark) if they're going bio. Its kind of a cheese strategy that will work perfectly fine if they don't scout your tech. If you've ever heard of totalbiscuit he has a series for low level players and there is an episode where he actually sort of deals with battlecruisers.

I Suck at Starcraft 2 - Episode 20 - Who called in the fleet?

To improve on his design a little, I did two proxy bunker barracks with the barracks much further from his base. Barracks with techlabs can give you some pressure. You can use a number of units from this or lift to make reactors. I don't make reactors, I make a few reapers for harassment.  I add starports at that place and lift my barracks to change over the tech labs. I can transition into bansees here, if the build goes too terribly wrong. But the proxyied fusion core allows for litterally no scouting. I try to pump marines and two base early because the early  bunker near thheir base allows me to have a massive economic advantage while they switch tech to siege tanks or stems - which isn't effective against my strategy as a whole.

The key is to make sure you have a barracks and an armory in your base so that he isn't able to scout air at all but thinks you're teching for bio or armoured. Remember yamato cannons basically one shot turrets and vikings.

For those using D3Advanced or any other bots out there for Diablo3.  It looks like Warden has been activated and is doing some kind of work. 
For those d3a users, d3a should have picked up unusual warden activity and prevented you from using it , thus saving your life from the evil woman that is warden!.
For the rest of you, gl!  I don't know the anti-detection method Immortal Bot has or others but warden is alive.

If you have more info, feel free to post.

ty for informing

Mooege is still trying to make retail d3 work.   Check their github, there is always something new being added or fixed.

so anyone knows what progress has been made so far?i feel like no one is working on it since no recent posts about it have been psoted...

I only use them in the campaign mode on the mission where you get them; when playing other people banshees and wraiths are far superior when mixed properly.

Edit: Vikings, not wraiths, sorry. I forgot the new ships name

It was just for Beta, but they´re working on the retail 

The game requires a server to run so it always needs to be connected to a server.  So what's being worked on is a server emulator called Mooege.  At this time Mooege doesn't work with the latest client, but steady work is being done on it.
You can check the Mooege section on this forum for more info or visit their website @mooege.org.

Maze will be awesome!
