Well on ARR initial release the training wheels pretty much were fully off by Hauke Manor and Brayflox Longstop. 28-36ish if remember right. The mechanics in those two tended to weed out the lazier ones a bit, and required knowing job basics and such then.

With all the rebalances and expansions, I'm not sure where it moved to. Depends on how far vets are just willing to carry people.
