i think i'm able to answer to this question, as i was an ADC Darius main before his nerfs, and a dedicated Dota2 player

What makes a melee champion good in the bot lane?
First, think about teamfights. You're going to face tanks in teamfight your team expects you to kill them as it's your primary role
Darius for instance has Armor pen, huge ad steroid, and true damage nuke
Mordekaiser has huge damage+ his ult deals 50% max hp damage in late game
Second, you need to survive against ranged champions
League's marksmen are the strongest champions in 2v2 because they have one of the strongest poke, because this poke is avaible at level 1, and because in 2v2 you will reach lvl 3 after a year
which means if you get poked too hard before lvl 3, you won't have enough hp anymore to fight
Darius was strong in the adc role (in high elo, i think he's still viable below ~~diamond 2 in the adc role) because he could fight them at lvl 2, and his 2v2 was unmatched by any adc as he healed on 2 champions with Q
Mordekaiser on the other hand, has shield, ranged spell to farm, and sustain, all of this makes him able to survive until lvl 3 where he can start to destroy people
Third, i would like to add that sieging power can be brought by any ranged champion
i like to have orianna in my team for instance, her sieging is really strong

Isnt playing him hard since you are possibly are going to go against 2 ranged champions so it will be hard to poke them?
what is hard is surviving until lvl 3, afterwards you don't poke them but you kill them

also you have low movement speed so how do u avoid ganks? :D
W gives you bonus movement speed if cast on an ally that is nearby, so unlike toplane you can cast it on your support and get the fuck out
you also can 2v3 in a lot of situations
