I checked previous act exploration rewards, and noticed a pattern:
-after Act 4 100%, we got enough material to have our first 5* r4 with 4 T2A
-after Act 5 100%, we got enough material to have our first 5* r5 with 2 T5B
-with Act 6 100%, we got enough to have our first 6* R3 with a full T5C crystal (highly RNG dependent tho)
So following this trend, we should get enough material to have our first 6* r4 champions by getting enough T3A and T6B. However, till now Act 7 didn't really give too much of these cats. Even if the 7.4 rewards follows the same increase as previous chapters, we still need to get at least 2 of each catalysts.
So I was wondering if we will really get to have our first R4, simply by exploring Act 7 (not counting Carina challenges, Summer of Pain and Grandmaster Gauntlet).
What do you guys think?
