So illaoi can have her tentacles untargetable during hr ulti...
...yet when
ultis her plants
s or ball just happen to land near them and they die almost instantaneously.
Edit : I dont expect
to really need invulnerable plants if hit by her ulti but maybe it should give them twice as much as health or something. Right now it feels unrewarding hitting your plants with your ulti cause they die in like 2 secs.
can get his R turret picked up by 
Qs in your team and all your plants dissapear
