Mark of the Kindred is very underwhelming and boring
We already have a dozen "get kills, get stacks" mechanics on champs and items, and %HP True Damage is one of the most cliche and boring mechanics in the game right now... I don't feel very rewarded getting a kill especially when the stacks are almost free from Scuttles or enemy camps.
And I don't know how long the novelty of the "mind games" is going to last, or if their enemies are even going to care.
I don't feel like she is bringing much to the game in this state and wish that Riot could have brought bigger ideas to the true "Reaper" of League of Legends.
