It’s normal. Sometimes the TC will spit out only 3* for weeks in a row.
Some will say “that’s just RNG”! And I suppose it is, just RNG.
Though RNG in this game, in my experience, tends to act particularly funny.
Real life RNG, if you flipped a coin 100 times, you’d expect it to land roughly 50 times on heads, 50 times on tails. Not perfectly of course, you might have streaks of 3 or 4 of the same result in a row, but highly unlikely that you will flip 20 times in a row and land on tails 20 times in a row.
In E&P however? Yeah it’s totally normal to land on tails 20 times in a row.
Then to land on heads in the next 20 flips.
And you can sit there and say “wtf? this looks broken…”
And the game will look at you and say, “hey, the odds were 50/50. You got 20 heads and 20 tails. Therefore the odds were correct.”
“Yeah but how come I got all those in a row…”
SG - “I said… the odds… are correct.”
“Just seems weird how it was so streaky like that…”
SG - "THE ODDS… ARE CLEARLY… POSTED."
SG - “We said that 1 out of every 100 summons would result in this pull. We did not say that everyone would get that hero. Regardless of whether 1 person got 1 and 99 got none, or one person got 100 and 9,999 people got none, the odds remain the same. Working as intended. Thank you and goodbye.”
The uh… so called ‘beauty’ of RNG right there.
