Okay, 4 stars completed icons doesn't need to be considered that much work. Soon they will be uploaded for chests. The real challenge is bringing clarity for small icons with 1 to 3 stars.I agree(it's not a good design and not very attractive too). Just tried to give example illustrating the point of having no icon. Some good design change will help to go with no icon concept. For good design, dev team can grind their brain. But it is clearly possible and work out very well.
For past few days, I tried different design changes, none suits better for mobile view. Still trying on it. Will share one example in the next comment though I don't feel fit correct.
