Solo que Ranked does have luck as a factor, but I wouldn't say it is entirely dependent on luck.
I've found that there are 2 major factors for victory in Ranked, being Luck and Skill. The most important thing I came to accept in these two factors are that I have control over one (Skill), while I have no control over the other (Luck).
Looking at these 2 factors, we can determine 4 pairings: Skilled and Lucky, Skilled and Un-Lucky, Not-Skilled and Lucky, Not-Skilled and Unlucky. Looking at these pairings, we can estimate the results.
Skilled and Lucky: Likely to Win (+)
Skilled and Un-Lucky: May Win or May Lose (neutral)
Not-Skilled and Lucky: Likely to Win (+)
Not-Skilled and Un-Lucky: Likely to Lose ( -- )
Knowing that we have no control over Luck, we can only determine if we are to be Skilled or Not-Skilled. Thus you can choose to be (A) or (B) as follows:
(A)
Skilled and Lucky: Very Likely to Win (++)
Skilled and Un-Lucky: May Win or May Lose (neutral)
(B)
Not-Skilled and Lucky: Likely to Win (+)
Not-Skilled and Un-Lucky: Likely to Lose (-)
Looking at the results, you'll see that A has a more predicted chance to win overall.
I know I'm grossly generalizing the entirety, but the concept is there. Don't worry about luck, as it cannot be controlled. Skill as we can see that it has more desirable results and can be controlled, so focus on this area.
