Darth Vader weak VS Douku/Sidious/Maul/Kylo Ren

Darth Vader. The one! Spawned by the force, destined to balance the force, murdered countless Jedi. Because he joined the dark side the empire dominated that Galaxy. The single most pivotal character in the Star Wars universe, is out matched by Count Dookie, Darth Sidious, and Darth maul, each of them has more effective advantages over Jedi than Vader. No one has killed more Jedi and no one deserves more fear than Darth Vader. He killed Jedi Masters, padawans and younglings. He even kills the emperor with his bare hands and brings balance to the force. Vader's choices change the Galaxy but he is not as awesome as Count Dookie???Really? He only gets one extra attack if he kills some one after a two turn set up that if he gets stunned or taunted erases the opportunity to do any significant damage. His regular attack is weak. The fearful swing should have plus 10% damage per negative effect. His AOE is weak. His AOE should give everyone attack down, defense down, lose turn meter, and 25% stun all, -10% critical chance, unavoidable by Jedi, instead of just three damage over time. His lightsaber throw, each time he kills someone, should reset along with the 100% turn meter gain. Additionally, his leader ability is so lame...on each enemy character turn, while he is still alive, at the very least, Jedi and rebellion should have to save vs various fear, weakening, Accuracy Down, -10% critical effects that beef up the lightsaber throw. Don't nerf Vader because the current movies aren't about him. Vader was the chosen one. The only one that could bring balance to the force. Kylo Ren is a star struck whiney little girl next to Vader. Why is kylo rens abilities better than Vaders? Why is count Dookie and Darth maul and Sidious more intemidating vs Jedi than Vader? It doesn't make any sense.
