You already know how OP Nilya when she hold her "Ice Ball" , so Lilith decided to make a overhaul on her skills.
Good news is: She can 1v1 on Ember (Ember going insta-regret for mocking Nilya)
Bad news is: No Chain destruction (Her "Ice Ball" can make 5-man kill)
Talk about overhaul, look what did I found(She will get overhaul in order to suit the skin):
So your saying tha she was OP in DOTA and they nerfed her abilities here.
How do you know she is mediocre if no one has tried her yet? Radulf was not mediocre btw.
Good point I should write on top of the post "This Is what I think"
Also My guess is mainly due to the fact that her abilities look average, She may be OP anyway.
her Armor and the fact that she only focuses on slowing down enemy instead of killing them
