A Summoner-Based Champion?
The champion that im thinking of is a blank slate but can be completed with more ideas and time but these are the basics
I feel like we lacked a champion who's main focus is to have a familiarity/pet to be up and be the main source of damage
Things like 
Bear Tibbers and 
Sentenal Daisy are only ult and 
Void swarm feels underwhelming
I am thinking of a champion who's passive is 2 wolfs that fight for them while in combat but if they are killed it takes 10s each while out of combat
Feel free to take the wheel and make this pile of... info and make it golden [sg-lux-2]
Im clueless of what im thinking... : ^ )
did we? i would count 
but Valor is more of a support than an actual fighter. and 
act as one with Willump being the main fighter and Nunu as a passenger/spectator. 
has Pix but Pix acts like Valor and is support than actual fighter. and with 
, Skaarl is a big meat shield. 
has Sand Soldiers but they only last like 30 seconds tops.
what about elise? One form can send a homing spiderling and spider form gets her swarm of spiderlings
