how do you counter a full armored Thornmail Rammus if your team only has AD champions? my team gave them rammus as a first pick despite me begging him not too and then they proceeded to give us a full AD comp talon, riven, vayne, zed and olaf.
Get black cleavers and last whispers on riven and talon maybe? Get a last whisper on Vayne. Olaf shouldve gone really tanky with an armor pen item. Make sure you all have a strong Lifesteal item: hydra on riven, Botrk on Vayne and Zed, Hydra on Talon. grab merc treads on zed and talon probably, and get maybe a GA or a Banshees on the squishies. IF you can, bait out the taunt on olaf and have him ult out of it, then wreck face.
...You don't. Bend over, apply lube, he is coming in and there isn't a damn thing you can do to stop him. On a serious note, your best bet is to buy a Banshee's Veil to possibly negate his taunt and counterjungle so he doesn't get to that god level I counter every AD stage, if you don't...hope that he is bad.
This is why I mained Rammus in Season 3/4. I CAME IN LIKE A RAMMUS BALL!!!
The counter to thornmail is magic resist and lifesteal.
Everyone on your team should have gotten Last Whisper, and Riven/Talon a Black Cleaver. Expect olaf he should have gone tank.
Everyone on your team should have had some sort of item that gives lifesteal, all that's left is some magic resist and you're golden. I'd suggest merc threads for his taunt.
I think where your strategy broke down was feeding rammus in the first place. yup
thanks for the advice I actually didn't know thornmail was countered by mag resist btw so thanks
Tenacity doesn't hurt either. Reduce the duration from powerball slow, taunt, 
and the magic resist helps too.
