Most of those points are what makes me excited about classic. I'd mark the graveyards/flightpaths mildly annoying since you will die a lot and also have to travel back and forth a ton. People forgot just how disjointed the leveling quests were. You had to jump zones and continents every 1-2 levels if you wanted to really optimize questing. Trying to do everything in a zone quickly ended up with you vs 3 or 4 lvl higher mobs that handed your ass back you. Damn I'm already salivating for another vanilla leveling run.
