I once had an idea that Paladin (Mage/Oracle) should be “Diviner”.
Its mostly for the “It sounds cool” factor, but ig for the word “Divine” too (Since gods use both magic and spirit and MC’s unique awakening from having both, it being called “Divine Spirit Energy”)
I don’t really care about the name changes but there was nothing wrong with the original names. They sounded nice anyways. If he’s going to replace them at least make them one word only instead of “Strong Warrior”, that just sounds low effort
If he wants to do this so bad.
Then just do
Paladin - Spirit Mage
Juggernaut - Spirit Brute
Knight - Spirit Warrior
Berserker - Brute
Conjurer - Weapons Mage
Warlock - Magic Brute
Warlord - Weapons Brute
Boom
10x better
