There are 5 sunfire capes. Just make the enemy your butt buddy and you will burn to death eventually. Or else you force them to let you cap because otherwise you will die to sunfire capes. So ya there is counterplay. Also the most obvious is simply not picking up the xerath buff in the first place.
Bami's Cinder maxes out at 23 magic damage a second and has a small radius. Also, the tanks can buy boots and just outwalk you to force you off them.
The lowest MR at level 18 is 38.5 That reduces Bami's damage to 16.6 damage a second. Health regeneration at level 18 is generally between 14 and 20 health every 5 seconds; let's go with 15, which is about equal to or lower then every champion's health regen in the game. They regain 3 health a second, always. The Bami Cinder person just has to walk up, have a single tick of damage happen, and then walk away. It takes another 5 seconds after being interrupted to be able to even start to recap a relic, with a total of 7 seconds of time to cap a relic to begin with.
But hey, let's disregard the "they can just walk to force you out of Bami's range for a while". Most champions health range between ~1800-2100. Let's go with 1800. Bami's does 16.6 damage a second: after health regen this is 13.6. It would take you over 2 minutes of standing in Bami's burn to die.
So you can, technically, die. It just require the enemy to never buy boots/you to be Cassiopeia, and you to sit inside their burn range for over 2 minutes straight. That's not really feasible, as realistically you'll never spend more then 10%-25% of your time in Bami's. Even at 25% of the time in Bami's it would take over 26 minutes to die. And remember, all of these numbers are assuming you are playing a ranged champion with very low health and health regeneration.
And for the final bit. Not picking up the Xerath buff requires your entire team know not to pick up the normally really important to get and have buff. And it requires anyone who doesn't know to listen, which is also unlikely. The only 'counterplay' it has is having your entire team know not to touch the buff, and know not to go near it in case the enemy team forces you onto it.
