Totally, I agree with that completely. I remember being freaking STOKED when getting plate gear in instances when leveling. However, leveling now is just a way to get a character to the real game to me. The game starts at max level for me and for a lot of people to. I always argued that I would actually remove the leveling part of mmos altogether. It feels like a new season in Diablo to me, I just get max level as fast as possible to get it over with and then start playing the real game. I even, like a jackass, let my friends level in season 6 while I was on a date and then had them power level me the next morning instead of spending the 3-4 hours to level
So for me, leveling is an unfortunate part of the game that I wish I could do away with. Heirlooms and super condensed exp curve is helping me with that but it's not even enough for me.
For new players, the current leveling scheme is terrible, it is not fun at all and they don't even have access to acceleration like we do.
Here is the problem, how do we make me (and other "veterans" like me) happy while still giving a meaningful leveling experience to new comers. Blizzard tried to make both sides happy but ended up making both sides feel terrible. I don't want to spend the time to level since I did it way to much (while it was fun even) and new comers or even veterans who enjoy leveling (those people are weird) have a fucked up, easy as shit and confusing leveling experience. How is it elegant to have a character outlevel a zone when being not even a third of it in . All the story and lore is lost because people are forced to move on to an other zone before being anywhere near finished.
My solution to that would be to simply, remake the leveling curve so it makes sense, remove the super powerful heirlooms BUT have us pay GOLD to level a character to max if you already have a max level character. People like me would pay the gold and get an alt ready for the real game instantly and people who enjoy leveling or are new comers get a very good leveling experience. Both parties are happy.
