Riot really missed out on the new dragons...

So i've been playing since season 4 and I was initially excited for the new dragons but now I kinda think they missed out on a really dynamic experience. Imagine instead of dragons, minor bosses show up. Sure they could do the same damage, health, buffs, etc., but what if instead of dragons this new boss shows up. For the water buff a swamp monster could spawn from the lake below. Add some torches around the pit and a fire demon could be conjured before you. The earth moves across the ground to form an earth giant. A mist comes up and a djin stands ready to attack. Each with different attacks; each with a separate strategy. And an elder dragon comes as the herald of the end! But we are left with a recycled idea.... again...
