Cant use spells on enemy core

How this still a thing? Cant play Jaina on PvP at all.
This bug is staing for 10 days or more since Bulava made a video about it.
Such a shame the game is in this state.

No PvP balances are really bad, but no PvP fixes are not aceptable. Guess is time to stop playing because the devs dont care.

Yeah - a Blue Post would be nice!
