Mi-Lo-De-Fu-Be-Ba, the Local Gang

Disclaimer: I am an amateur game designer but have extremely rudimentary understanding of what makes a good champion mechanic within League. The abilities below are undoubtedly horrible ideas, but I've included them to demonstrate the spirit of how I think this champion ought to play. Feel free to revise the abilities to a more sane design while keeping the feel of the gang of Yordlings.

Elevator Pitch: Meet Mi, Lo, De, Fu, Be and Ba - a gang of 6 adolescent Yordles that travel in a pack, terrorizing locals and causing havoc. Utility champ, energy or cooldown based (mana makes no sense).

Auto-attack: One of the gang members fires a rock from a slingshot.

Passive: "Anything you can do I can do better!" The gang is unaffected by critical hit chance increases from items, instead gaining critical hit chance as they level up. If the gang scores a critical hit with an auto-attack, one of the other members will take the opportunity to fire an additional auto-attack at the critted target, which has a (diminished) chance to crit. This can repeat up to three times before a cooldown kicks in.

Q: "Let's teach em a lesson!" One of the gang members performs a flying dropkick on a target, doing damage at impact and slowing the target by 10% for 1 second. Each successive keypress sends another of the Yordles at a target, up to all 6. Successive hits on the same target add slow percentage and extend the slow timer but do reduced damage. If used more than 3 times (i.e. more than half of the gang has performed a kick) then no other abilities can be used until the gang re-gathers (done by making a move command).

Notes:

• Individual gang members can be damaged (XX% reduced damage taken when hitting any individual game member) and CC'd while dispersed, slowing or temporarily preventing reformation.
• Additional abilities always originate from the gang's location
• Any movement command will bring dispersed gang members back to the core.

W: "Oy!" The gang launches a challenge (medium-range skillshot) at a champion. If it hits, the target is damaged/taunted and runs at the gang (X seconds) creating aggro for the target (i.e. minions will attack the targeted champ). While the target is taunted, W can be pressed again (short-range skillshot) to send two of the gang members behind the target while the remaining 4 give a hearty push, tripping him/her, causing damage and briefly stunning the target.

E: "Looks like someone is a little lost..." The gang marks a target for X seconds. If the total number of friendly units nearby (champs + minions) outnumbers the number of enemy units near the target (champs + minions), the target receives XX% increased damage for each unit they are outnumbered by. Lasts 3-5 seconds.

R: "All together!" The gang members assemble (Voltron style), gaining movement speed, attack damage, armor and MR. All abilities are replaced and have revised cooldowns: Q kicks, shredding armor and doing damage; W punches, shredding MR and doing damage; E is a headbutt that slows and does damage. This lasts for 20 seconds, or until the gang drops below 30% health and they break apart, falling to the ground. If this happens, the gang is stunned for 2 seconds. This mode can be manually canceled by recasting R.

All Together formation (o = 1 Yordling; - used for spacing) --o-- ooo -oo-
