Would luke be more powerful than Yoda if he had proper training?

No, I honestly don't think Luke was more powerful than Yoda in any of the movies. EU is another story. Yoda has more experience in everything.

Dude, definitly NOT! Yoda was pretty much the head of the Jedi Order, and he was small and still almost defeated the Emperor. So no. Yoda would still come out on top. but if your talking about Luke being more powerful AFTER Yoda died, then still no.

I really hope that SOMEONE makes episodes VII, VIII, and IX.

Yoda is definately better than luke. he has hundreds more years of exp so he would be way better

if luke had been trained for long enough he would have turned to da dark side 😈

We never see Luke at his full potential in the movies. Based on the books I've read, and the fact that midichlorians are real I'd say Luke eventually bests Yoda.
You can argue that Yoda was older wiser, blah blah blah blah friggin blah, but right under Yoda's nose a Sith Lord took over the galaxy and converted the Messiah of the Jedi Order.
Any Yoda > ROTJ Luke
NJO Luke > Any Yoda

the only person more powerful than yoda is sidious and no one could of learned much more in anything to become better than thoes 2..and if yoda wuld train luke foryears i dont think he would teach luke everything he knows and since he trained luke he would know every single move luke knows

Not true, Anakin was more powerful than Yoda, but he wasn't as controlled.
NJO Luke is far beyond Yoda in power
