Allowing then to be other classes will not cost then a raid tier, they now have to work on the dragon form to wear armor and done.
They chose to make the visage form have to many customizations to hide their laziness on the actual dragon form, that is what we call smockscreen tactic, because its a re-used demon hunter idea sold as race.The visage forms being reduced is choice based however. They could've definitely just put horns on every race for visage but instead decided to make them a unique racial appearance, probably to make the race look less cheap (even if the visage forms were "lore friendly" and could be anyone, I can see a lot of players calling it a lazy race because of how few new art assets would be used). But because they did that they had to reduce the visages down to two.
We already saw in shadowlands that adding a wide range of customizations for multiple, IS NOT HARD.
Doing this half-asset end up being worse than making what people wanted, so now they have to run for their money to fix it.
My dude, you don't know how this class will be, just by the presentation we can even say its going to be lame half-asset that just have 2 specs
It does not even use fire to heal like you wanted to. Youc an't even change to a gnome like Chromie that you used as example, or other visages like the dragons we saw so far.
Allowing other players to play like they want - with other classes or visages - will not remove anything from you, stop being selfish
The way they designed is bad and limiting, so they should changeIn lore, dragons like Alexstraza and co. are only dragons. That's what the new race is designed to represent.
Its how things are.

Like i said, if you are happy, good for you.
Changing so other people can be happy as well will not ruin your happiness
unless you are salty about tinkers and this is why you are in this crusade for the new race/class to be bad, so you can point that out later.
