I wouldn’t call the couple thousand summons that the thread has registered a “small sample size”.
I think we can pretty safely say the odds are 75-20-5 for 3*-4*-5* respectively.
They’ve stated multiple times that TC20 is supposed to be the best way to obtain 5* heroes. I have seen no reason to doubt that figure, and having run 3 TC20 continuously for the last four months the figures roughly approximate my experience fwiw
You’re well ahead of the curve odds-wise at the moment. Don’t get too disheartened when you hit a 3 week stretch of Tyrums, as is bound to happen, just know that over the long haul it will all even out
I have gotten 10 5* heros from around 120 TC-20 pulls. I am satisfied with the odds already. In the morning I am resuming use of my four centers in anticipation of gaining a red hero like Azlar (to use my six rings on).
Way way too many 3* coming out of tc20. I stopped using tc20, because the 3* are just way to costly. For about 6 months i have gotten nothing but three stars from tc20. The cost of food and recruits is just not cost effective.
