after 8.24 
darius Ult - noxian guillotine the maximum dmg (red words and numbers on his ult description) doesn't calculate his passive bonus ad and it only calculates after applying stacks to the opponent.
it has always been like that.
Dude, fking same, I have trinity force and sterak , + 1 infernal drak, it should be more than 1100 true dmg, but it only shows 800 true dmg, I had to actually test it out on practice tool, its the same, it works normally, it just doesnt add the extra AD you get from your passive into the calculation, i was in the middle of a soloq game when I realized it, I was so spooked.
I NOTICED THAT TOO AND TOLD RIOT MAPPLENECTAR TO LOOK OVER IT BUT HE DIDNT SEE IT .. NOW DARIUS FULL ITEMS IN RANK 3 ULTIMAE SHOULD BE MORE THAN 1K DAMAGE BUT IT ONLY STAYS AT 800 WHICH I STOPPED PLAYING DARIUS FOR THAT ULTIMATE (BIG NERF)
patch 9.7, still hasn't been fixed
