One thing that I have come across that aids with slogging through the leveling grind is using a paladin leveling guide. When you have decent gear and a clear path for questing, the levels tend to speed by a lot faster. That said, if a leveling guide isn’t a viable option for you, you do have the option of going for a free mod like QuestHelper. This will at least tell you the areas and most direct routes to finish your current quests, which should be enough to boost your leveling times by a good amount and get you to the coolest part of the game soon enough to enjoy it before the next expansion.
