The new era of specialization
We want the talent trees line up immediately on your chosen style of play. Already the first distribution of point should be significant. If you choose the amplifier, you shall immediately feel like an amplifier shaman, not after another 30 points.
..., you will receive about one talent point for each second level rise (41 points total at level 85). Our goal is to give you turn to a talent point or a new spell / a new skill for your class per level. Another important change is that you have to invest first 31 points in your primary talent tree before it can award points in another tree.
