As this is my idea, I like it a lot, but worry this BRB may be quite powerful.  Interested in what everyone else thinks.  Having a long lived player who you coach every season maybe very tempting but does mean putting a lot of resources into one player and a single injury could be ruinous.

Doesn't seem  like a terrible idea. I wonder what the impact on the game might be (if any). Top talent at age 6+ would unique. What about something similar but as a Superstar BRB. Just a brainstorm here: 

~ During the age I and II seasons, a superstar does not lose Skill Level points during aging. Stanard aging begins after the age III season.

~ A superstar may only be assigned when a player is age I, and must be selected by the Captain's deadline.

~ A team may only have one superstar on the roster per season. 

~ Not sure how to deal with trades that involve superstars. Maybe superstars cannot be traded? If they can be traded, how to address the team that now has two superstars?

Just some thoughts.

This seems a little too powerful. What are the numbers like with ageing 1 less rather than 2 less 

And/or the maximum captain's bonus being 5. SL 20+ seems high 

Brian - watch this space for other ideas around superstars 

I think 2 is the right number if you link it in comparison with the Ciach who is adding benefit to your team throughout the season, not just at year end.  As for the Captain´s bonus, potentially this does see big, but as James mentioned the risk of adding the bonus to such an old player is catastrophic if he gets a bad injury. It also costs a lot in terms of CP to get him fully fit in the first place, unless you sit him out of the first 6 matches of the season.

Personally, I love this idea but do have concerns around how increased player longevity might affect how many young players you have to bring through the ranks every year.  As balancing youth development is a core part of the game, getting this wrong could cause issues that might not become clear for a few seasons. I like Steve's suggestion of only ageing 1 level less as it would minimise that risk.

My feeling is that if you only age i level less this coach is just too weak potentially in comparison to others. I would not worry too much about balancing youth development. I think you only really need to bring through three youth players each year and there are often youth players to pick up in the auction too that you can pick up to balance things off.

I like this idea but think that perhaps it is too powerful. As an alternative, to Steve' suggestions, maybe just allow dietician to operate on one player rather than two.
