In WoW, daily your way through the levels. Though you usually pass through zones, do the quests available, and never return again, in some places you’ll find daily quests, marked by blue exclamation points, where you can do the same quest (or one of a selection) once a day. If you do the same dailies every day they’ll definitely get old, but it can definitely be a nice change of pace from the usual leveling grind — plus, dailies tend to give you boosts to reputation and/or other rewards as well.
If you don’t have a lot of time to play, dailies may be a perfect fit into your schedule. No matter what level you are, you can log on and do cooking and fishing dailies in the major cities — you’ll get experience, reputation with that city, and skill-ups to boot. You’ll also find daily quest hubs for levels 60, 70, 80, and 90 that are worth investigating if you need a break and you’re in the right level range.
Mostly because you’re locked into a quest a day. It is, however, an efficient way to get both experience and other extras when you have limited time to play. These are very complicated, you can choose WoW power leveling service can help you save time.
