And paladins aren't even close to the top in low level pvp.
You're fighting people who are awful.
I know lol, I've been !@#$ting on hunters who don't use
Serpent Sting (which I cleanse anyway, but whatever, cleanse has a CD and serpent sting doesn't)
Daze shot (hand of freedom it usually, but still, might as well try)
Other paladins or ele shamans who for some reason don't heal themselves at all... or cast a heal when they're at like 10% hp and I just silence it and kill them lol
here's a sampling from a few games I played today, everyone sucks so bad, but still, healing classes are unkillable except by large numbers and it's not right
