Plenty of people don't think giving more options as 'altering'
I understand and know that is true. I guess I'm pointing out that adding options sure sounds like altering to me. I mean if you didn't have the archetype, how does it get options added without an alteration?
Quite simple. The base ability is unchanged. If I stick a bumper sticker on my car, it functions 100% the same as before I added it. Same for skill list + one new skill. You say altered and I look at you funny. A new option didn't change the starting options one bit and left them unaltered.
