It’s just random. I get great boards when I stomp on people, and awful ones on the rare occasion I’m chasing cups.
Same thing with titan damage, lot of it is just RNG variation between the low and the high end. Today I had a fun farming one against a non-trivially weaker opponent in power terms and cup value: 5 blue in a easy gem to make on the first turn with Athena vs. a red tank (Colen). Tank dead turn two, left side dead on turn 3, right side dead by turn 5.
I would’ve easily won anyway but this one was just silly.
That’s all just RNG though, occasionally even against both weak and strong teams it’s like the game wants me to lose but on average my boards are just that, average.
