Quests for t4 class catalysts

Hellboyy9999

I have been playing this game on a daily basis for quite some time now. And I know that if I don't spend money, I won't get the best stuffs. But still just to make it a bit easier to rank up champs. Like ranking up a 4 star champ to rank 5 and even the 5 star ones, it would be very kind of you KABAM, if you could start quests which include t4 class catalyst fragments as rewards. I know what I have said might not happen yet I would love to have atleast a reply on this matter. Thankyou.
