Sasuke even without his inherited KG would be the most versatile Raiton user in the entire manga, with six completely separate Raiton attacks under his belt, three powerful Katon attacks, proficiency at Shuriken jutsu and Kenjutsu, (Godlike Speed according to databook) Lightening fast speed, and advanced Taijutsu, together with high intelligence that enables him to break down his opponents brick by brick. Hence at a mere age of 17 bordering on 18 - if I go by the current time line - he would still be high Jounin.
Unlike him, many characters would be absolute crap if you take away their Blood-line limits, who do not rely on anything but that. But, since you are only centering your abysmal efforts on Sasuke, I see the reasons behind it. Long story short: Your Thread --- Endeavours and conception = utter crap. Can we at least agree on that?
