What triggers some people about Pathfinder?

I mean, sometimes it’s the math. Adding 30 different +/- modifiers that could be 1, 0, or -1 is the very definition of complicated. It’s not complex, but that doesn’t make it easy.

Okay, much as I'll rag on 3.P for being overly complicated, I don't think you're gonna be dealing with that many at the table. Between sessions, maybe, but not at the table.
And I'm okay with more complexity in creation and level ups, since you have ample time to handle it then.
