2 points into a skill tree is nothing to have access to higher skills. In D:OS1 you had to invest far more to have access to higher Tier skills. It's part of the 'dumbing down' of everything. Having only a third of the knowledge of a skill tree but already being able to master even the most fierce skills just sounds odd. It also means that 5% more damage is pretty everything you will get for leveling up your skill trees even more which sounds pretty uninteresting.
