From a not very competitive players point of view, the 6* r5 gem are actually amazing for me. I have a lot of champs that are 6* that could benefit from being r5, however i don’t want to waste cat resources on them when i can use them on 7*. Not every account will have every sought out champ that are exclusively 6* to the highest rank. So these resources are good for those players. And that is where the target for the quest comes down to. If you don’t see it as value then don’t play it. It’s not like they took away from the typical showcase to add this. It’s additional content for those who want to do it. Both the main showcase and deathless quest (if you at least have 1 deathless champ, gives a 7* r2. So focus your resources on those.
6*s are no where near irrelevant, but 6* rank up gems are irrelevant. If I want to r5 a 6*, I can just use cats lol.
I'll never understand the mindset of "6* are done". An Ascended 6R5 already equals a 7R2 (basically), and a regular 6R5 basically equals a 7R1. There is virtually no content that is too strong for that. So why not take the opportunity to use/rank strong Champs that don't exist/you don't have as 7* yet.6* are absolutely still worthwhile, unless you're a super whale who has nearly every 7* Champ at R3. Pretending they aren't is just a weird elitist mindset.
