I think the teased ranked rewards (banners and icons) are a little "underwhelming" given how many hours we need to put in the game to "grind them out".
I understand you can not give out any crazy rewards, given there are currently also much more important points in the game to work on.
However, I think there is a pretty easy way to make the rewards feel more rewarding: Simply by adding Quantum Cores to the rewards
- there is currently no other way to obtain Quantum Cores except for getting lucky with ion cores
- reward grinding by adding more Quantum Cores per rank
- no extra work for designing etc.
This could e.g. look something like this:
Bronze: 1 Quantum Core
Silver: 2
Gold: 3
Platinum: 5
Diamond: 7
Paragon: 10
Given that most players are Gold or below you would give out only relatively few Quantum Cores, but still provide them with at least the chance to get some very cool skin etc. and reward the small percentage of players that manged to climb higher with more cores, additionally to the planned icons and banners
