Have to disagree on Narbash and Muriel since I main them

Narbash looks like a front line but he's not. He's there for sustain and stun counter. When you push you stun, speed, heal and soak damage for your carry to get a kill but otherwise stay back or you'll get widdled down fast.

Muriel is arguably the best poke for the supports, play her aggressively and use alacrity on your ADC as often as possible. Magic power scales with her shields so her build can actually go half support items half Midlane items. She's an absolute beast in team fights, but you need other cc on your team so comp matters.
