Not really. Gamers can just create new account & share info via public forum. These guys only have their life.
If there are class (wealth) differences, the wealthy probably have their secret vault of knowledge & past trial for a particular skill tree that they specialize in, like the MC family favoring offensive sword. Wealthy probably more inclined to specialize in offense as they can hire other roles. Adventurer, on the other hand, are likely to either have mess up tree due to lack of knowledge or well balanced (offensive, defensive and a support) tree given how easy they are to die & the mission turn from "hunt/gather" to "survive".
