As possible, keep increasing the level cap but crunching just how much experience is needed per degree. This is the strategy classic wow gold has taken. However, as this occurs, amounts begin to seem meaningless. You gain them ultra-quickly, and a smattering of them introduce new abilities or perks. It also suggests that you blast through the leveling content in a speed that you don't ever complete individual zone tales; you simply finish a small portion of an area until you have outleveled it and are prepared to move on.
Blizzard's fresh solution in Shadowlands is to return the level cap to its initial value of 60 and to make current content suitable for amounts 50 through 60. New players start at level one, plus they play via a brand new introductory zone constructed for Shadowlands based on the quest design course Blizzard has learned over time. Once they play through this introductory experience, they could then level around 50 to grab with current content by playing the prior expansion (Battle for Azeroth) immediately (from approximately level 10).
This skips all of the content prior to the prior expansion to give players the latest encounter from a pursuit design POV (also to be certain that the buy wow classic gold players are connected with the present storylines). Additionally, it ensures players that are new have a leveling ramp--Blizzard says it will be up to 70% shorter than it's now to get to the cap.
