I think summoners still exist but the Institute of War does not. This would mean weak summoners are still employable (or they might find themselves replaced by some hextech automation from Piltavor with help from
and possibly
...siege engines maybe...)
I would like to see One minion stand too close to an exploding Nexus and Become a champion.
Name: Winion
Height: X2 of regular minion (slightly bigger then Yordle size)
Role: Support main
Story: After a horrible ACE at the enemy nexus the enemy team ran strait for his home base thinking they killed all the minions. Smugly leaving one behind as, "what could he possibly do?" Winion, then minion, walked stalwart into their base and proceeded to smash at the nexus. By the time the next swarm arrived and before his last ounce of health was taken from him, he gave the last blow to the doomed Nexus. Needless to say the summoners controlling the enemy team payed a heavy price for their bronze 5 mistake. The explosion was grand and left him sentient, not vanishing with his fellow minions. Days would go by as he waited alone wandering Summoners Rift until a new match started. When the next match was up, he simply walked around aimlessly as both sides would attack him, so he hid. When he was finally found neither side could claim him and in a very Very rare case, the match was halted to determine what this absurd anomaly was.
It was then decided since he was in fact sentient and capable to survive on his own he should be removed and studied further. None were more interested then Heimerdinger who graciously allowed him to stay at his home after the match as an assistant so long as he shared his findings. As Heimerdinger's assistant, he would be the first to test the latest equipment such as Winion's Axe, Wand and Book, Souped up Siege Engine, and translator communicator that helps Winion speak to other minions as well as the occasional animals and monsters that Heimerdinger might have in his lab.
Winion became something of a showcase in Brandle City. With visiters coming far and wide to view the strange site of a minion outside of the Fields of Justice. The attention was good for him as he learned to interact in a social manner but a bit bothersome to Heimerdinger as it interrupted his studies, but he would bare this for Winions sake so Winion could learn what it means to socialize and be a member of society. Desiring to repay the Yordle community for its kindness he has joined Heimerdinger in the League as a champion for Brandle City with his master's inventions in hand.
Passive: Remember! Winion has been blasted by towers and smashing on the Nexus and Inhibitors countless times. Sharing his wisdom, he gives his fellow champions around him 2% endurance and damage against objectives that are near him.
Q: Toys in the Attic! Winion switches from melee to wand and book which will scale respectively from (X AD) for melee and (X AP) for wand and book. Enemy champions attacked by Winion are taunted towards him for (X) seconds and can not be taunted again with the same type of attack in a row. (cool down 15 Seconds)
W: Come Together! Winion can either inspire his fellow minions or convert enemy minions permanently. When activated Allied minions gain (X) times their stats which will swarm an enemy champ for (X) seconds. Permanently convert enemy minions that are targeted will have half the stats, and worth half the gold when slain by the enemy, who will swarm an enemy champ for 2 seconds. (for each enemy minion converted by the activation of that spell gain 1 gold and share with champions in range) (cool down 20 Seconds)
E: Back in the Saddle! Winion Summons a souped up Siege Engine with bucket seat that one allied champion can choose to ride in by clicking the seat. Siege Engine Winion gains 10% speed boost that degrades over (X) seconds and launches cannon balls for (X) dmg plus (X AP) which slows enemies by (X%). The ability ends after (X) seconds of driving off. (Allied Champions can attack from bucket seat) (20 second cool down)
R: Sweet Emotion! Winion Inspires ALL allied lane minions to be super charged Minions that gain X% stats plus X speed) for (X) seconds that will redirect focus to the closest enemy Champion or objective that comes into view. This can also be done to converted minions.
Joke (near minions): Winion will martch back and forth like a regular minion wile squeaking something similar to hut 2 3 4.
Joke (Winion pickets with a large sign that says, "Save the Minions" marching back and forth.
Taunt: Winion points and makes a squeaky laugh at his enemy wile holding his stomach.
Dance: Winion starts squeaking Sweet Emotion into his wand wile grooving with his music.
