Giant Form is +1d6 not +6 and double Str mod is + 5 for less than +10 average damage lol. "elder brain died on like 6 hits" can your fighter do that? Nope. Outright impossible, blatant lies as demonstrated by your own screenshots. Just saying "your math is bad" doesn't actually replace providing any sort of evidence or analysis or rational arguments you know. Saying something is true doesn't make it true, no matter how much you want it to.
