Now that the support players are more rich, I found out that I'm able to support with Darius. Think him like Thresh or Blitzcrank early game. He can pull them in over the minions, slow them, and turn fights into his team's favor at bot lane where both sides are on low health and fights end with very close hit points early on.

You are basically at the bot lane just to make sure your adc can farm safely. Just wait for a mistake from enemies and try to capitalize on it when they make one.

Don't try to initiate unless they don't make a mistake.

Pros:
Good poke damage
Pull them over the minions
A good slow
Win lost fights on bot lane with his ulti
Carry as support

Cons:
No sustain
No disengage
No

Talk with your ADC and let them leave the big minions on each wave to you whenever possible. Don't forget to kill a minion when your Relic Shield's passive is up. This way you are giving your ADC kill+5 gold, getting gold from kill yourself and healing them.

* Don't use spells recklessly or you will go our of mana easily..

* Keep your tri-bush and river warded at all times and keep an eye on them. You don't have any disengage abilities so you have to see the gank coming. Do not put your ward to the small bush near the bot lane. Ward the river close to dragon so you see the gank coming. Use your trinket if you are suspecting someone at that little bush.

* Keep lane bushes warded whenever you are freezing the lane so you don't need to ward the river. Or at all times vs supports like Annie, Blitzcrank, Thresh, Leona etc.

* Every time you go base make sure to spend your money left from items on wards and mana potions. And health potions if you still have money and space.

* If your jungle wants to gank but can't initiate, flash and pull one of them in to set up a kill for your team.

* Count respawn timers on Baron(7mins) and Dragon(6mins) and announce them a few times in chat before they respawn. Make sure your teammates know what you know.

I use teleport over exhaust so my team won't lose a turret everytime a teammate makes a mistake in their lane.
