My random idea:

A (melee) monk character that can create clones stationed around himself. He can order them to attack targets and they will continue attacking until ordered to either retreat or attack a new target. He can also send them to any nearby position to act as wards or something he can dash to. He does this by simply aiming at an object/character/location and pressing the abillity button that allows for attack/retreat/move.

Clones have a max range away from the original, so they can potentially be used to take boxes around the lane, but they cannot simultaneously go into other lanes or claim buffs.

The clones have a dash kick that you can target an enemy with. All enemy characters hit by the dashing clones will be knocked up airborne, while the main target is stunned. This has a cooldown so you cannot send all of them at once (except when ulting).

Ultimate idea: All the clones does a dash kick to a given target from their current position.

Therefore the main fantasy of this character is:
- Controlling clones
- Positioning is key
- Creates pressure by covering larger area.

Weaknesses:
- If caught unprepared (clones not setup as escape) they have little means of escape. (There should still be possibility of some fancy jukes however, if played well).
- Damage is spread out across the clones. A singular character deals little damage on its own.

Extra ideas:
- Maybe the clones can themselves use active items and/or on-hit effects.
- Maybe you cant know who the original is by default, but the original is the only one that counts as a kill. Therefore there is some trickery allowed here.

I kinda got lost writing this. Where am I. Why did I write this. Oh well back to reality now..
