When people cry about
:
If you can't deal with him in lane simply stay away from him. If you can't fight him 1v1 who cares? This is a team game and any half-decent jungler will camp Darius anyway.
If he is fed and roaming simply walk backwards and laugh as he tries his hardest to catch up.
If you somehow actually got caught by him, flash or dash out and once again laugh as his fatass tries to catch up.
Don't be that player who lets Darius basic attack him 5 times and ruins it for everyone on his team. If he has 3 or 4 bleed stacks on you, rotate out and force him to start from square one on a new champion.
It is often better to stay in handle range of Darius instead of try to get away from him and get hit by the blade, and CC makes this even easier. Play any teambuilder game and you will see people do this all the time because they can't use bans as a crutch and learn how to deal with Darius, whereas primarily ranked players are used to him being off the table 93% of games and never forced to learn how to fight Darius.
Focus him in teamfights. The only way he will survive long enough to basic attack someone 5 times in a teamfight (against anyone above Bronze6) is if he is getting the max heal on his Q, meaning he's hitting 3 of you and as such is deep into the enemy team and separated from his own so you lose nothing by focusing and killing him.
He prioritizes HP over resistances, so %HP magic/physical damage and
will shred through him every game.
And last but not least:
#DON'T CONTINUE FIGHTING DARIUS WHILE HE IS IN BLOODRAGE
Darius is hilariously vulnerable to disengage, and if your comp lacks any sort of disengage then that's your fault.
