I understand the mechanic behind treating Advanced Skills as Untrained Basic Skills.
It allows an untrained person to attempt the skill, at half-stat.
But once that skill is Trained, it no longer provides any bonus.
Once example:
I was looking to play an Explorator, and thought it might be nice to be from a Forge World, where he will get a head-start with the knowledge of both Tech and the Machine Cult.
Forge-Born characters gain Common Lore (Tech, Machine Cult) as Untrained Basic Skills.
Explorators starting skills include Common Lore (Tech, Machine Cult)
Despite growing up on a Forge World, and a game mechanic being in place to supposedly give a bonus for this, my Explorator knows no more about Tech or Machine Cult than any Hive-Born or Void-Born Explorator!
How do other people see this? Is it such a cheap bonus as to not worry about? Does it seem wrong? Has anyone House-Ruled a new way of playing it?
