And some more for 10 (or adjustments for 9, where feasible)...
30) More 'accurate' fan happiness. For example, I lost 2 points when I traded a first round draft pick, but I traded for another, better first-round draft pick. I lose two points for every first round draft pick I trade away, but earn nothing for bringing in first round draft picks. The scale could also go higher or be more insulated. For example, at 100, if I keep winning, nothing happens, but if I lose, I dip below 100. And so on.
31) During NHL shoot-outs, I receive a message after each goal informing me that one team (usually the one that scored first) is now ahead as if they had scored a 'real' goal, which is not the case. The shootout commentary should reflect the status of the shootout.
32) Better (or at least more contextually-phrased) tactical advice with more varied messages. During games, after almost every period, my assistant coach suggests I should reduce backchecking (which I have set slightly above average), either because I am outshooting my opponents or because I am being outshot by my opponents. When suggesting I reduce, I get the same message as if I am significantly outshooting them, even when only doing so by one. I don't mind the advice itself--that might be a factor of the assistant's preferred style of play--but there could be different phrasing for different situations.
33) Customizable (and saveable) views for rosters, etc., including options to see 'hidden' information when in commissioner mode. For example, related to #4 from my previous post ('Clear delineation between ratings for international team and club team, with easy access to both...'), the consensus rankings aren't all that helpful when I'm managing a low-level international team and a higher-level professional team. Instead, I might want to see 'international ability (stars, scout)', 'international ability (stars, consensus), or even (in commissioner mode) 'offensive ability' and 'offensive potential ability'. The data is part of the game; we might as well be able to see it and use it.
34) Ability to edit fitness (in commissioner mode). It is possible to remove injuries, but not to bring someone immediately back to full health. Yes, it is cheating, but that's part of commissioner mode.
35) In commissioner mode, a way to force other teams to trade among each other (or buy/sell players where applicable, or sign/draft someone, etc.) without taking over the team in a way that fires their GM, and without involving a currently-controlled team. For example, I manage Team A in commissioner mode but want Team B to trade with Team C. Perhaps this and some of the other suggestions require something above commissioner mode (e.g., 'deity mode') /> to differentiate between commissioner powers and those not even a commissioner would have.
36) Scouting that can extend beyond 20, or could reach 20 through hiring instead of points.
37) Transparent connections between coaches, what they are coaching/training, and the effects. Especially helpful if I have more coaches than officially-assigned roles. (Do the 'extras' also benefit my team? If so, which ones do what? Or do they sit there and do nothing? And so on.)
38) Ability to add competitions after the game is underway, every July 1. This would likely be limited to nations not currently hosting competitions. For example, I might want to add more u14 national teams so a more diverse set of players will be created (e.g., from South & Central America). It seems weird to have so many countries present in the game with no clear way for the game to create more of them, even if some already have players (e.g., Jamaica). Maybe even just a set of 'world hockey academy'; teams to generate players from nations that don't have u14 teams?
39) Option to add even deeper international competitions. I'm sure it would come with the quality warning, but it might be fun to play in some (very) non-traditional hockey nations.
