is lancelot the weakest 5 cost hero?

idk if im just lucky or not but without yellow cards, probably lancelot is the weakest 5 cost hero on board, he got no cc and temporary cc/dmg immune unlike other 5 cost heroes. aurora 3 stars literally wiped the whole enemies' army, lancelot cant do that in short span of time. lancelot 1 star can die easily unlike other 5 cost hero. what do you guys think?
