Interesting way to replace stars... I like it though not ALL promo icons hold true to the gold so we'd have to adapt those that don't such that the gold layer is more prominent so it could be adapted to this method. Examples of those may be found among the First Aid lines I think.
We often have more than 4 tiers too... consider some of our promotionlines extend up to 10 layers so we'd really need to plot out a full 10 color categories to achieve this. Either that or work with a set of 5 or 6 and then add a symbol that universally means we're onto the second set of 5 or 6.
Then what happen to color blind players
