Title pretty much sums it up.
Classic and BC have had me recently browsing the talent systems though the years. In LK we got glyphs stapled on and Cataclysm was the first big change when the number of available points were squished. Then came MoP where we switched to the proto version of what we have now but you could borrow from each of your class specs fantasy powers. Then finally WoD brought the version we still have today. My point being every few expansions we seem to get something new, I'm wondering if after what's being suspected as an 'interlude' expansion(before some weird changes happen to the wow universe) we aren't due for a different take on talents again.
