I really do miss the old talent trees. Not so much at max level but while levelling alts. You used to alternate between getting a new talent point to spend and a new ability to learn/use. It really felt like you were getting rewarded for each level you gained even if that reward is a +1% to crit. Now you can go 4 to 5 levels without getting a single thing to make your character feel more advanced and more powerful. It really has made levelling more of a slog and a grind then it used to.
