4* Ultron - Rank 5?
With the newest news regarding the 5* hero crystal change, and the lack of information regarding if shards will become more attainable. I am at a crossroads on if I should Rank 5 my 4* Ultron that I have recently obtained the final T4CC I've been waiting for.
I think the best course of action is to wait and see, but it's hard to keep waiting for the R5 I have available.
