The kit

Mystic is a really interesting melee class. The class has amazing control around her. Her succession has amazing damage where her awakening is more about control and support. Personally I don't think awakening having strong damage for PvP is what Pearl Abyss envisions for the spec. I like that awakening is more supportive in PvP, being a tanky class with good control and with low damage. However I do think that her intended presence and pressure isn't living up to the expectations. These changes is what mystic needs to make the intention of Pearl Abyss a reality.

Changes

Gushin Water

Mystic awakening doesn't really have frontals. The proctection is mostly Super Armor. This is good to be able to soak damage while still being a threat. However I do think that she should get a skill with frontal guard in awakening. Since adding a new frontalguard would be a bit excessive, I was thinking about changing the Super Armor of Gushin Water to Frontal Guard. This would give her the ability to react to threats and incoming damage since Gushin Water is an amazing skill that flows off of other skills. This would also make the gameplay more fluid by giving awakening the chance to block damage rather than soaking it.

Raging Wind and Dragon Strike

Awakening Mystic's new skill called Raging Wind was introduced with the intent of pulling monsters better. I have yet to experience this "intention" with the new skill. The range is pretty cool but you don't pull monsters using Raging Wind. It's also not practical to use the skill in PvE to pull. This cool idea Pearl Abyss had, could be turned into something better for PvP. The skill has no damage which is totally fine. However adding a stiff on Raging Wind would make the skill usefull. Adding a Knockdown on Dragon Strike after Raging Wind would give awakening more utility to control the fight around her, better.
