I'm kind of tired of reading this ******** and moaning about mezzing and stuns, because as far as counteracting mezz, you don't really need a spell to counter it, really, has anyone heard of that little RA known as Purge? And as far as stun goes, pretty much every class has some sort of stun attack, whether it be through straight melee or some kind of spell. Sure it maybe easier for a caster to launch off stun, but bear in mind in 2 or 3 swipes by an lw tank the go down like a ton of bricks, or hell even shield slam is one of the best stuns out there in game. Each class has a unique set of abilities, it just comes down to how well the player can manipulate them. And as far as soloing NF as a tank it is still quite possible, just make sure you have Purge and IP and you really don't have much to worry about from SBs or Infs or NSs unless they're high like Azrailis mentioned such as rr6+, and if you're finding a fire wiz and such is one shotting you or even in like 2 or 3 shots, then maybe you should invest in some items to increase your heat resistance. Just because you're taken out quick doesn't mean RvR is unbalanced, there is never a time you are invincible.
