Senna is a bug in ARAM
Extremely long range + AOE healing + able to trigger on-hit effects (for example, Duskblade of Draktharr) from extremely long distance away + AOE rooting + AOE damage + camouflage + AOE shielding + bonus movement speed + basic attack and abilities ignore Yasuo's W
Can you imagine all of these on one champion??? I understand Riot intentionally make new champions OP so they can sell more, however, this is too much, especially for ARAM, when you have no bans...
That's why Senna is the most played champions in ARAM in the last 7 days. And that's why Senna got unbelievable 53.16% ARAM win rate when most people still have no idea how to play her...
Riot, could you please ban Senna in ARAM for a while? or at least bring bans back, so I can choose to ban her every game...
