Class rework and new gameplay

[Tankylikehulk]

I have a suggestion :
-War class divided into 2 classes:
barbarian which is a physical damage class(using swords)
paladin which is a tank class (using aegis)
-Rogue class divided into 2classes :
Assassin/shinobi close range attack (using daggs)
Archer long range attack using(bows)
-Mage class divided into 2classes:
A support one (using staffs)
And a magical damage one (guns)

Why I suggest this is because I heard that there would be a rework on skills and it would fit perfectly with the proposal especially since the next maps will be more difficult and can bring diversity to the game.
Maybe some maps with physical or magical damage required in order to beat boss or mobs,some with healer and tank needed

To unlock specific class maybe at lv50?
And for those who are above lv50, the possibility to change directly
Lemme know what u guys think tyvm
Sincerely
