Hi,
Yesturday (20.03.2014) I played ** Strom 126 (boost in the event) lvl, maxed blue ability in pvp game and only one character received damage. Other characters in oppsosite team were supposed to die after receiving over 2000 damage but they didn’t like nothing happened. Character I targeted received damage and were stunned for 4 turns, 11 blue mana were spent. It was one time issue.
I had similar problem before (1-2 weeks ago) with Original Black Widow when her blue ability simply didn’t work at all. There were no countdown tiles on the board. Click ability, nothing happend, 9 blue mana gone. I had this issue several times.
I play on PC trough STEAM.
Cheers
