Just what the title says. Now I'm not talking about companions that can promote (though some of them apply to this to a lesser extent), I'm talking mostly about companions that can't promote like the batacuda and crab hermit for example. Now normally when you first recruit a companion you're given the option to train at least 1 extra epic on them, however for some like the 2 that I mentioned above, this doesn't happen.
I was wondering why is this so, as I don't see the point in not allowing these certain select few companions not able to train at least 1 extra epic in addition to one(s) that they come with. Thanks in advance.
