They should be expected for every new expansions by now, right?
The one thing players seem to actually miss about the old talent system was that you got a point to spend for every level gained. Sure, the old talent system was just boring little percentage increases in stats with a new spell thrown it at certain points down the trees but, having that 1 point for every level gave the player a sense of progression. Now, we have 1 point for every 15 levels that will give us some form of passive or a new spell. Not really all that exciting is it? Though I do admit that it is a far better system than the old trees. As far as I can tell from complaints, that is the only real issue people seem to have (please don't try telling me there were no cookie cutter builds with the old trees. It was "use the build on the internet or gtfo").
What will happen is that they will change it up so that you have a better feeling of progression. Whether by using a Path of the Titans-like system (oh, how I wanted that...) or just changing the amount of talents by giving you one every 5 levels, for example.
I know some of you lovely people have ideas on what to do with talents so feel free to mention those ideas, but for everyone else, just like Winter, change is coming!
