If a person never played pathfinder or dnd and just wants to play, let's say, a mage-type character he will have to choose from Alchemist (6 subclasses), Arcanist (6 subclasses), Bard (6 subclasses), Magus (7 subclasses), Sorceror (7 subclasses), Witch (6 subclasses), Wizard (7 subclasses). That's 45 options for an arcane spellcaster. If you aren't into rulebook reading and decide to read about every class you will get bored, if you just randomly pick one you will be frustrated by the fact that you may have picked wrong. You can't win there if you are just an average rpg fan.
A big problem here is precisely the thinking that "you may have picked wrong". What do you even mean by "pick wrong"? That the devs intentionally put an extremely poorly designed class in their game to bait players into picking it and punish them for their choice? What's wrong with just picking "wizard"? Again, it's a fundamental class; thinking that one of the fundamental classes of RPG "may" be a "trap" class that would punish you down the line is silly.
That's in theory. In practice, I've picked a bugged class (arcanist) on my first attempt. I didn't immediately realize it, because I don't play pnp and the class mechanics were new to me. I've since restarted, because I don't enjoy playing a character whose class feature isn't working.
I've since checked the Owlcat forums, and seems like a lot of class-related bugs were reported in beta. So it is not like the devs were not aware of most of them.
