Azir Broken Soldiers

Okay, normally I don't care about Azir cuz I don't play against him. I eat him alive on a normal day. But, today was different. I was trying something different. Mid. And I am doing it with a champion I have never used before. Annie. I picked up the basics of Annie and proceeded to do pretty decent at the beginning of the match farming and getting kills. Now I am not new to league, even though I don't know everything, but I am no half wit when it comes to picking up a new Champion. Annie is fairly easy to play and I liked her right away. But she isn't the problem, nor the reason for this post. Azir. I think he is pretty decently balanced in most ways. what I can't understand for the life of me: why can't you target his sand soldiers? The ONLY untargetable summoned minions in the game. And they lunch for you like a Skill shot, but with little to zero chance to dodge because of no indicators. I have tried playing Azir, wasn't for me. That's fine. I'm not mad I can't play him. Totally cool with that. However, A Summoned minion that can extend reach, can't be targeted or killed, can avoid turret shots while poking away at champions and minions, reaches really far even without Azir, AND GET"S THREE OF THEM!! This isn't broken? How is it fair to Yorick, Annie, Heimerdinger, Elise, and all the others that can Summon minions but don't have those bonuses? Like seriously? Can ANYONE explain this to me?
