I am convinced..
... that t4cc crystal chances are rigged based on what you have in your inventory. Today I needed to form a mystic or a mutant to get my first r4. I already had 3 of them. So I would have gladly accepted either one of them after opening 12 crystals. But nope.. Nothing, just more of what I already had.
I don't even want to post pictures as there are tons of posts opening even more crystals and not getting what they want. But this needs to change. This just adds to player frustration. For those that are going to say its just rng, I only have two r3 five stars, one mutant and one mystic. So obviously the game knows which one I want to r4 and it skews the odds against me pulling those required cats..
If this game isn't about pulling and upgrading champs you like then its failing its purpose by not letting us do that.. Creating unnecessary bottlenecks is just plain and simple BAD.
For the mathematician in the house, I believe my probability of not getting either of the two catalyst is (4/6)^12 = 0.77% approx. Correct me if I am wrong.
This is not okay and Kabam needs to respond about this and change things up.
