Most balanced

Correct, it has enough classes of each tier that you can make balanced parties

Nerf wizard spell list, and they can still bend reality and not take away the super hero feeling from other classes. Best of both worlds.

>tiers balance the game
>not WBL

It actually doesn't, because per default everyone gets the same amount of money. If you create a party going for consistent tiers, you don't have to change the system itself

What is 'D&D 4e'?

It actually is, ttrpgs aren't competitive games, you don't need to be the very best, you don't even need to be good, it's a roleplaying game, you know, as in roleplay, try doing that.

But core 4e sucks, you need the later monster manuels and erratas

Nope, tiers mean nothing in a game with a GM who by default introduces the encounters and actual content of WBL.

There is no actual reason you can't provide good encounters to a party consisting of classes in different tiers. Everyone basically doing the same thing only really works in a video game, not tabletop.
