No I'm not saying that.
I'm saying I don't want everything to scale with me. Like it used to be.
A furbolg in Ashenvale who is level 22 should always be level 22, and when I outlevel him so much that he is worth no experience anymore, I should be required to move on to another zone. The furbolg shouldn't level up with me. I go to the next zone, and there are stronger monsters. Those monsters also are always at the same level.
Therefore the reason to level up is to become strong enough to defeat those stronger monsters.
If I am level 30 and there is a monster that is level 50, I can't defeat that monster at level 30. I can try, but it will demolish me. So now I have a reason to go level up until I feel that I might have a chance.
Like we used to have red quests in our questlog, but we knew we'd never be able to complete them at our current level. So we had something to look forward to. As we'd be growing in level we'd be seeing that quest go from red to orange and go "maybe now I can do that quest".
Instead of having everything scale. It makes leveling up unrewarding, because a level up matters less. People always complained about the lack of rewards in the form of abilities when you level up, because there were so many levels and so few rewards. But what people often seem to overlook is that the level up itself can be a reward, because gaining one level can make a significant difference in terms of your power level which can even enable you to do certain content.
If the people on your server for example suggest that you at least be level 15 before you attempt deadmines as a dps, then that becomes something to look forward to in and of itself "I just dinged level 15, maybe I'll find a group for this content now", or even "I feel confident in tackling this content now that I am this level".
That is all gone with level scaling. Level just doesn't matter. The only levels that matter are level 10 and level 50, because 10 is when you unlock access to everything, and level 50 is the level you need for the endgame. Actually playing between levels 1-10 feels more satisfying than the entire 10-50 bracket. Even more so when you play in classic.
The reward for gaining a level shouldn't be that every mob in your area also gains a level.
