Issue: people can ignore all lethal mechanics and Aeona can soak heal what are typically 1 shots over 15 seconds.
This causes a vast majority of players(mostly new) to never learn the game and end up in a group where they are expected to interrupt but have never used the skill or know which ability are even lethal.
Solution: If the damage from 1 hit is greater then 100% of the characters hp bar. It still 1 shots.
