Just reached LvL 100 on Girl Symphony ! Nice

I must say I really like the meta shift from FKG. The event Girls here are much much stronger than in FKG since the lvl of the skill directly increases the Damage. As such unless you have multiple dupes and skillblooms invested into a gacha Girl she will be outperformed by them.
In FKG most of the event girls bare few exceptions are weaker than Gacha girls by rather huge margin.
So yeah, its nice to see the Event girls be of use other than a placeholder.
