Theres a few things that “could” happen depending on the interpretation of the announcement…
1.- Some class could be “rearranged” to other base clases
2.- With “reinforce the role and the purpose”, could mean that each class will offer a specific “role”, i would guess damage dealer, debuffer, buffer, healer, CC… could be more idk…
3.- Going back with another dev blog, where they said that they will tone down the cleric dmg, it could mean that going with point 1 and 2 that some dps class of cleric could be “rearranged” to another base class…
Going with all together, they maybe can put support class of wiz to cleric, and cleric dps to the rest of classes… Also it may depend of the new base class, mi bet is it will be a “complement” of swordman, taking the new class and current swordy, mi theory is that one will get swords and mace and the other will get spear and shields…
So basically anything could happen with RE:build
This is just a theory and by no means it means that it will be like that :V
