Cyclo sword into profane into endless hunger with either BC + long sword or LDR
i did some damage tests and Bc + long sword on target with 1500 bonus hp and 230 armor did 3400 dmg with 5 AA into R AA Q1 E E Q2 AA Profane AA AA
While ldr did 4350 damage on the same target
Now on another target with 130 armor and 300 bonus hp only BC + long sword did 4300 dmg with 5 AA into R AA Q1 E E Q2 AA Profane AA AA
while ldr did 5200 damage
now a full combo R into AA Q1 E E Q2 AA Profane AA AA on An Adc with 110 armor and no bonus HP
BC+ long sword does about 4000 damage
LDR does about 4300
LDR damage goes UP by 5% for every 300 extra hp 20 armor the enemy champion has
LDR does 12% more damage to enemy champions with 130 Armor+ and bonus 300 hp
LDR does 21% more damage to enemy champions with 160 Armor+ and bonus 600 hp
LDR does 25% more damage to enemy champions with 190 Armor+ and bonus 900 hp
LDR does 33% more damage to enemy champions with 220 Armor+ and bonus 1500hp
Black Cleaver is better vs squishy Bursty champions because of the hp ability has while doing only 5% less damage then Ldr
LDR is WAAAY better vs anyone who build 1 or 2 items of Hp + 1 Armor item
if you are playing Vs squishy champions and more burst go with Serylda grudge
these test are done with 25% crit so they are not that accurate but will give a genral idea of how much better ldr is vs HP stackers, Yesterday i played againset a 3 item+ Nasus and i Had 2 items and a half and i won the 1v1
