I do think we need another 3v3 format. I like Europe, but it is the only well known 3v3.
The reason why we've all been trying to get Warlight to support a 3v3 Europe ladder is because that template is hands down the best 3v3 template we can think of. Unlike 1v1 and 2v2, there's not a huge argument going on about what template is the best way to test your skill in 3v3. So if you're trying to find a standard competitive template with little argument on test of skills.. well here you are:

If you keep asking about 1v1 you'll constantly get different answers, but with 3v3 there really isn't a better 3v3 template.
^ I said this in a topic about strategic templates.
The problem with 3v3 is that there hasn't been another template that we are comfortable saying is strategic.
With that in mind, I challenge the competitive community to bring forth a template of 3v3 played on a different map that is comparable to Europe. If you do so, I will urge everyone in league A to vote for it.
