I dont see how that would save her ass at levels 13+ where she really falls apart and costs her team the game.
As it is, she is mostly fine until late game... but could use an interrupt to prevent people from popping potions in her face or escaping from a battle she won. She has high damage from spikes, but it is not a burst, It takes 5 seconds to dish it out so it is easy to get around since she can't stop you from using items/skills.
From another viewpoint, she has the most amount of useless skills. There is really only 1 way to play her, and so far I don't see many people doing it the right way. (probably because they don't have much experience with her, or have done a hard mathematical analysis like lifekatana has done)
Regardless, I am not a tier 1 player, but if a tier 1 player were to use Lifekatana's build along with his and my meta game strategy with her, she would belong with the other tier 2 demigods.
Additionally, to be clear, I don't think any build or strat would put her as a tier 2 demigod in the hands of non-awesome player though, She is VERY hard to use with Lifekatana's build to reap the rewards.
Lifekatana's and my guide is coming soon. It really is being worked on. Lifekatana and I are talking back and forth to complete it weekly. I am excited to see some tier 1/2 players put it to use to see what happens.
