Playing Support when top/mid feed
What are people's suggestions on how to hold off a team and possibly win as support when you have a troll jungler and your mid and top lanes fed?
I shall give an example:
Had a Rumble top against Trynd, the Rumble just fed like crazy and even said he wasn't even trying to win.
Zed goes to help but ends up giving Trynd first blood and even more kills.
Rumble's excuse for not even trying was because our jungler went Soraka..
I happened to be Illaoi support with Cait adc against Blitz support and Kayle adc.
The opponents mid laner was Veigar and he was allowed to farm mid safely.
Their jungler was Elise and she got to roam and gank undetected because no one else but me was warding.
Me and Rumble ended up switching lanes but by the time we did, Trynd was already about 4 lvls higher than me and the top tower was about half way gone. My team eventually surrendered at 20.
support and have success getting a snare when maybe 1 or two enemies are together and since my team is so far behind we are grouped and swarm them and get a kill or two. You do this a couple of times and your team starts slowly catching up.
