I'm sure this has been reported to Lilith on other channels as well but just in case: the ultimate of the new CS hero does not prevent team mates from using their ultimates, but it keeps their energy constant. Thus, ultimates of team mates can be cast without expending any energy, making it possible to cast 50 ultimates in a row. 50 Sylphi ultimates in a raid stage leads to records that can't ever be broken again, so this is something you should fix asap (preferably by tmr, emergency patch).
Does Lilith not have any beta testers?? Or do they do this on purpose, releasing crazy bugged heroes, adding some DP events and then fixing them after everybody has bought into it. Like they did with Hurok and then Petros. It makes me sick.
