Ask Capcom. Kushala Daora had a sub (though technically it doesn't really count as one, it's just shedding), on the other hand Lao, Fatalis and Jhen both had subs of their own. If it is really true that Goa belongs to the elder dragon catagory, at least we know there are exceptions.

One thing which confuses me the most is we might be seeing some changes with some elder dragons. According to the test play report from Famitsu, Goa have some behavioral trates that resemble elder dragons, which is the immunity to traps.(It seems like one editor learned that the hard way, his shock trap simply exploded when Goa trample over it.)  But on the other hand, according to what we saw on the livestream videos these days, Goa might be the only known elder dragon to exaust itself. This raises the question whether all smaller elder dragons in MH4, like Teostra, Kirin and Kushala Daora could be exausted in the same fashion, or was that a unique behavior that belongs only to Goa?

I'd be quite happy if the other smaller elder dragons in MH4 also show signs of exaustion. At least those guys won't be such a pain in the butt like we used to face in MHP2G/FU.
