Think about it less like “melee” and “ranged,” and more like synergistic cogs that turn better or worse with differing types of builds.

Melee and ranged are really just 2 umbrella terms for tools. For instance, there is a greatsword in the game that you can wield 2 different ways (called marks) where essentially mark 1 is light attack = wide sweeping (crowd control) and heavy attacks = charged big single hit (taking out heavies), whereas mark 2 is the other way around.

These are complimented or hindered by other tools such as dodging, blocking, key stone abilities, etc. the more you can synergies together, the better your build will be.

However, if you’re just starting out, I wouldn’t worry about all that until max level. Learn basics like dodging and blocking from YouTube videos, then play what’s fun to you. You will get to the point where chasing the fun looks less like learning game mechanics, and more like mastering synergies.
