Are they discouraged because they can't play alongside the best, or because they can't play at the same level as the best?
In any case, a basic introduction to the game's concepts would be enough. From there, it depends entirely on how dedicated they are to the game. You only learn by playing and losing, so I don't think donating a few points makes a difference here.
I think the biggest motivation is actually enjoying the game. From another perspective, I don't really have any challenges, other than Valirhant and Vinme, so that could be discouraging, but I really enjoy the game, I enjoy the community, and that's enough to keep me excited.
