Don't get me wrong, not only I would not mind but I would LOVE if mages were given more than 4 non-spec trees, including Entropy. But I don't get what all the fuss is about, ultimately nothing has changed. A more appropriate icon (and possibly name, too, we're guessing Primal) was given to a Lightning & Earth based tree, when it was called Entropy and had another icon. It's about what's been imparted. This (small) change, is a good one, the way I see it...
The whole Discord/Discipline woulda been better: seriously? First off, there's a question of familiarity with these magic schools. Secondly, imagine i.e you'd have to go through like 3 fire spells you didn't want for a completely unrelated, non-fire spell. That would've been worse, IMO. So things have been streamlined. A couple things had to go, yes. But lesser of evils & all. Most of the changes, I think, are coming together & shaping up in a rather nice way.
Ice Wall? Static Cage? I'm like, drooling over these spells! Lots of cool new stuff which maybe wouldn't have been possible, had they settled for just the one Elemental tree, for example. Again, it's looking on the bright side (which IMO by FAR surpasses any "cons"), taking what's been given to us (and there's plenty of REALLY cool stuff to look forward to) and making the best out of it. Another thing that bugs me: saying "this or that, they didn't do out of laziness". I mean, really? You HAVE GOT to be pulling my leg when you look at something like this and dare question the amount of hard work that went into it. It's like, some people can never be satisfied. You just gotta complain! Make sure it's a game that's really bothering you. Cuz I dunno, honey... 
At any rate: Stonefist, I'm certain it hasn't gone anywhere, will be right there in the "Primal' tree. And I'm still holding out hope for a couple signature DA spells such as Crushing Prison & Walking Bomb being in the specs - though I'm not counting on it. So far, to me, this is all already looking too great! 
November 18. You and I. Cannot wait!
