Who should i get lucian or azir

Lucian is definitely easier to do well with

Neither is what I would call "easy". But Azir is trickier. Also... do you prefer mid or adc? that would be the more important part of this decision, in my opinion.

They both are easy to play and pay out well

Neither they both are pale in comparison to their release.

They have two very different playstyles

that's like asking do you want jam or a tomato on your toast.

Uhh do u main mid? Get Azir.. Main adc? Get Lucian.. See that wasnt so hard.
