Honestly I’m not the biggest fan of job systems in RPGs or other ways of customizing movesets like that because a lot of the time I just don’t know how I want to play a game. I’m really indecisive and just honestly have no idea how I want to customize a build, so I just pick what sounds coolest in terms of upgrades and I don’t have much of a plan when doing so.
There are some games that are exceptions, Vampire Survivors is a game I enjoy customizing a build in and I enjoy it in D&D but for most games I play that try to get me to customize a build I won’t deviate too much from the standard options.
