Illaoi's E suggestion
To be honest I was rather dissapointed when the duration of Illaoi's E was changed from 60 seconds to 12. I think the bigger problem is when she rips the spirit from you she almost always kills it, making it nearly pointless to contest. Instead the spirit should be harder to kill, for example by lowering the time you need to destroy it before the ability expires. If you still think the duration is an overkill you can change it so less tentacles spawn and become less agressive as debuff is closer to expiring (with appropiate visual cues) .
