Usually in conquest I end up playing support because nobody else will, which i'm fine with. I'd rather play support than have somebody be horrible at it or worse, intentionally feed.
Lately I've been bored with the traditional guardian supports and have been trying different warrior supports. Guan Yu was an obvious one, but I've found that Hercules and Ravana did well also. Hercules' pull and stun combo can keep enemy junglers and supports off your adc and he has incredible lane sustain. I was able to constantly body block for my adc when low health and heal right back up.
As Ravana, I didn't have to worry about enemy support's hard cc and I could bully the enemy adc, stun and let my adc rack up kills while keeping enemy adc at low levels/build.
I'd like to try Nox next. Her silence and root should make her a capable support, although I worry about not having strong frontline in late game, so I'd have to wait to try this until I get a guardian jungler.
What are some other unconventional supports? Also If you have tried any unusual supports i'd like to hear what they did well or where they lacked or maybe what you would have done differently. This is all about fun, but at the same time, I'd like to perform well enough to give my team a good shot at winning.
