I have recently tried to main azir.
i asked my platinum friend, when do you get confident on a champion?
he said around 50-100.
i ask for tips on maining azir. but he said "what elo are you"?
then said i recommend you not maining azir.
"main azir when you are gold" i am bronze 1 right now
and i asked why?
he said, "even when mastered azir is just a mechanically difficult champion."
so i got kind of discouraged to learn azir.
Azir received alot of nerfs due to his supremacy at the professional level of play. Due to this he now requires a lot of coordination and expertise to function properly which isn't obtainable at lower elos or solo queue.
For this reason you are correct in the fact that it may not be worth maining.
dont listen to your friend, this is a game after all and if maining azir makes you happy then do it.
besides its not like you bronze playing against plats, your playing against other bronze so its not like everyone on the other team will playing perfect mechanically.
i have made up my mind.
i will main azir. i will learn him in depth and try to become a better player in general.
There are also mechanically easy champions that are awful. 
for example.
It doesn't really have much impact on their overall power level.
You got a nice advice
