[Class Upgrade Option Confirmed: Corrupted Elemental Sylph]
The reason as to why she chose this class was due to the fact that it gave her more diversity when compared to choosing Ice Queen.
Plus, as a Sylph, she will gain more control over other elements including her ice element. After all, becoming an elemental sylph meant access to all elements. Of course, 'all' as in the ones she could use. Glacial, Metal, Lightning and Shadow.
There was also one more reason for her choice. IF she had chosen to become an Ice Queen in order to reach the extremity of Ice, that means she would slowly lose access to her Metal and Lightning attunement which is needed for her Nanomancer Class.
As a class that she knew she could reach the apex with, she wasn't about to give up that chance. Especially since she had another option that she could choose.
