Yes... the leveling out Wow until cataclysm featured a lot of features that really slowed down the pace. It is important to drink water and WOW TBC Gold eat food after a few pulls particularly at the beginning. Be cautious about not dying too often. There was a time when there was a leveling guide that claimed to to reach 60 (or 70, based on what you prefer) within five days. It was also played (or 120 hours) fast. It's definitely time-consuming.
It's classic...mana is important. This isn't an infinite dps bar like retail. This is the way that all classic players want. Each mob should be close to the cheap Burning Crusade Classic Gold player in control and at minimum 70 percent. TBC is much more simple than classic, and it's more lenient in terms of mob damage and mana regeneration. Even leveling seems easier to me.
