she is now broken against certain items and a summoner spell

the reduce on the time of slows stuns etc for mercury treads and cleanse will cause morganas ulti not to work as well as her first ability not doing full dmg

for her ulti all it does is stun and slow for about 3 sec then the sound is played but no stun or extra dmg

idk about the first ability but i think it should do full dmg even though its duration is cut

The Cleanse part is not a bug at all, but I think the Mercury Treads part is just an unintentional side effect that will most likely be fixed.

i really do hope so even with cleanse it has the same effect as the boots after it removes it but even if he uses it then i get him it will still be the same
