ive got some ideas for mechanics:

-skillshots/dashes which u can bounce at walls

-an aoe blind like heimer but using around urself e.g. a sandstorm around urself

-a taunt, which u can place somewhere and let the enemy position

-2 champs who can only be played if the other one is taken (if its work)

-a flinge-like ability: stun the enemy and flinge urself to the front.

-making something with the heat system which makes u faster at 50% and slows u on 100%

-a champ who cant auto-attack but using many sorts of bombs/mines and his ultimate is bombing himself up and doing massive aoe dmg or the next 2/3 hits let him explode (hey creeper im talking to u).

ive got more ideas, some of them in my thoughts already told.

if there are any ideas already told let me know.

Ir0nHead3

a skill that increase opponent's skill cooldown by extra 5 seconds.

what you guys think about this 1? could fit zilean xD

another idea about a skill:

Skill reflect.

returns the skill effect to the skill user.

for example morgana throws her stun at me and if she hit me and i activated the ''Skill reflect'' she will get stunnend instead of me being stunnend.

how about a support with shens ability to teleport,
this would increase aggresive gameplay.
as it would allow the support to back consistently to buy wards etc.
and give solo lane or your carry a reason to engage with the support ready,
and i mean a true support i.e healer sheild'er stunner etc

Meddler, how about such mechanic:

"transfer pain": toggle with few sec cd, you can cast it on your teammate and when he's in the range of "X" you'll take "X" % of the dmg he took from other players / minions. This would be great mechanic for tanks.

If tank get stunned, feared or silenced toggle will turn off and player will have to re-cast it again.

What I would really, really really like to see is certain skillshots being able to bounce off walls and such. For example, a new champion could have a passive which allows for skillshot bouncing.
