some abilities i was thinking about
1 Fools Fight - a copy of the champion (either self cast or target cast) controlled by the caster a clone that when it takes damage heals for 50% of the damage taken to the champion. if champion takes damage the clone will heal for 50% of the damage taken by champion. not sure if this should be a clone that can do damage / reduced damage / or whatever.. but having a copy of yourself that when damaged could be another step into something.
2 weighing down - directional spray on the ground the more a person walks in this their movement speed is reduced. so rather than heavy slow a the start the slow actually become progressively worse the longer someone stays / moves in it.
3 Force Grab - click on enemy champion then move them in a direction think of viktors laser how you click on a spot then move it in another direction and the laser shoots from one point to another. now imagine in you clicked on a target and could basically fling them in a direction. think about it. or it can be a complete skill shot and not only hit champs but could hit minions as well.. like a gust or something. http://25.media.tumblr.com/5d1f6e22b04bd9a3aad66b8599963317/tumblr_mv4r44HzYg1rp7jnqo6_400.gif
4 Beast within - receive a passive based on a jungle mob selected. imagine getting a perma buff or altered perma buff / passive of a selected jungle camp. raptors ... getting a auto ward scanner every 45 seconds that last for 20 seconds or just a companion blue... additional mana regen red ... additional damage gromp ... a natural thornmale golums... every 4th hit stuns whatever is being struck. Wolves ... get a flying century that you can move the way LB moves her clone. scuttle .. additional movement speed keep in mind i imagine this as a passive and can be only obtained by marking and killing a jungle mob... so you have to kill it for it to work.
5 shed skin - leaving behind old skin but increasing movement speed and attack speed..so reducing mr and armor. this i also hope would appear like bursting out of ones skin and doing a hop forward for that little mobility. could be used just to secure that last hit but making yourself squishier in the process so if miss judge can be punish. also can be used as an escape for that additional hop. i also think leaving the skin behind either as something that slows or blocks a object from passing thru it. then the skin grows back gradually reducing movement speed and attack damage but increasing resistances.
Remember this isnt about calling something OP or lacking. Look at all the other champions and there is something that uniquely separates them from each other and many at multiple times have been called OP for what they bring to the table.
Kindred is coming out who can get a perma 7.5% current health damage increase to her target, with a targeted ability that can prevent death.
(i dont make full champion concept because i feel limited and making random abilities i hope to only inspire)
