the sense I get is that it’s more like Pathfinder with feat trees
It’s a class based levelling system, going from 1 to 20, where you get a skill and talent at 1st level based on your starting class, and then develop with every level you gain. You can mix classes as you level up and each class has different paths built into it. You can’t jump ahead to grab a later feature without first taking an earlier one, and you can’t stack the same feature from different sources for double the effect.
Are there differences? Yes. Is it very different? No. There is more to say how it’s similar than how it’s different. There are class systems that are very different, but this isn’t one of them.
