T2 Dust has been around for a while now. This is a resource that's strictly for 6* champs. Since 7*'s have been here, and many players are no longer using rank up resources on 6's, and we keep getting it as a reward, it often ends up in overflow where it either expires or we're forced to use it. I think it's time for the OPTION to sell it, or trade it in.
It takes 3 T6CC's and 6 Basic and T3A's take a 6* to r5. T2 dust is to take a champ to "r6", so it seems like it could be "equivalent" to maybe 4 T6CC's, and 7 Basic and Alphas? These or half in fragments and gold, would be a decent return on a resource many are no longer using.
Thoughts?
