The skill tree stuff makes me feel like Bethesda finally listened to all those players who bitched about it being too easy to become "overpowered" and blamed it on how easy it was to level up and not the poor balancing with how level scaling works. So now, all the actually good, fun and useful shit is all the way at the top (or rather the bottom) of the tree, with a bunch of "milestones" you have to hit in addition to simply being the right level and/or having the previous skills in the tree.
