Last I wanna share a curious bug that almost freezes my game and force me to disable the addon. Anytime I add a (Citadel Crossbow [of the Fireflash]) my fps go from 75 to 22, and It's on a paladin, paladins dont even use crossbows. I noticed everytime I put something in my bags the addon takes the math and my fps goes from 75 to ~22 for a while (3 to 7 seconds) and is think it's internal and also think it's fine.
All I'm saying is that Blizz destroyed Levelling in my opinion. Having the option to get it all out of the way so quickly was a good idea, while still having the option to clear it all like one normally would. WoW is a game that's meant to have options, and ours has been severely reduced to 2 options; "Heirloom On," and "Heirloom Off." They even killed RaF exp gain and it no longer stacks with Heirlooms. They even killed the SoR for no reason at all. Feelsbadman.
If you buy a ready character in World of Warcraft, you take all the risks, because the first owner can easily always get his account back, and you will be left without the character and without the money that you paid. That’s why we strongly recommend to order a character levelling instead of buying WoW character, so you will be the first and the only owner of your World of Warcraft character.
Common methods of power leveling include doing only those quests which are most efficient in terms of experience over time, and analyzing the quests in a given zone so as to do them in the most efficient order possible. Remember, the idea of power leveling is speed and efficiency--you may wish to obtain an addon that will show you how much experience per hour you are gaining to test your techniques. Additionally, ensure your character's talent build is crafted for maximum endurance. You want as little downtime (walking, drinking, eating, crafting, typing, etc.) as possible.
90-91 i collected treasures that gave resources and then dumped them all in xp potions and began to clean up shadowmoon valley while also doing bonus objectives, after shadowmoon i went to gorgrond and did the same thing and then to talador for a bit before I was 96 and went to quest in arak until I was 98 when I picked up my artifact and went back for the last few levels. Overall 90-100 took like 4 hours.
As late as possible. Early on, you’ll want to follow the missions in Battle for Azeroth right up until you get the option to send a follower on a two-hour long quest. As soon as you get there, stop doing the War Campaign missions. You can come back to them once you have reached something like 119 and a half and finish leveling with those if you want. If you don’t use these missions to cap off your leveling journey, then they’re the first thing you’ll want to do once you reach max level.
