I dont want to go back to the topic, because it started with salty comment. No one is forced to spend 9k diamond for a Conjuring hero. Also, there was no surprise about the new chest hero come since every month contains one.
About Adeline: Got her at 4 star 92 o+1 and Yesterday I beat lvl 100 in arena.
I think she is good. If she got hit from the first abilities she restore her health back with her flute. Aoe stun is also nice, sometimes it stop Taurus in ulting. Rarely saw her ulting yet. Matches are too fast.
