At level 6 Darius has 84 base damage
At level 6 Darius does 15 damage on 1 stack per tick, with 5 stacks he does 26 damage per tick thats like 130 damage before armor
At level 6 Darius does 201 damage on his Q
At level 6 Darius does 117 damage on his W
At level 6 Darius have 5% armor pen
At level 6 Darius does 100 damage true damage, with 5 stack he does 253 true damage on his ULT
all this could work on an AFK target who does not fight back
Im not sure why are you randomly higher up his damage across the board without actually testing him in PBE
84 Base, Add A dorans blade, a phage, 2 long swords, any kind of additional AD, not even counting if you were to have Grasp on the PBE, you would be doing well over 100 Damage on Auto attacks.
15 Base +30% of your AD
100 Base + 120% of your AD, which again, at this point is most likely higher than 100.
Even at 87 Base damage only, Darius W does 121 Damage, not including the additional AD which will be in his build.
His ultimate does not do True damage until 5 stacks, I grant you, but at 5 stacks, it gives 20% additional damage per stack, meaning it does, at minimum, 100 + 75% Bonus AD, multiplied by 2 because of 5 stacks. Assuming 13 bonus AD ONLY, that would still be 226 True damage.
This does not include potential Rune Bonus', such as- Press the Attack, Coup de Grace, Last Stand, Electrocute, Predator, Cheap Shot, Scorch, or Grasp of the Undying.
If your issue is with his damage, try taking a different Keystone, Press the attack seems rather good, as you should already stack his passive.
If your issue is with his playstyle, I recommend another champion.
