also pbs works. I solo olga flow on my racast since lv 120 and when i get to that phase i wait for pb to get to 100 and shoot a dolphin in his dark flow ass and gg :)
when i first reinstall the game couple weeks ago i had some issues not like you but i coulnt play. Ive added ephinea to defender exeption, tried again but didnt work. Then i reinstall the game and it worked as it should. Hope it helps!
