Is AI the short for Artificial [...] behavior? Fix Sinesha!
Made a arena fight on auto instead of manual and watched what happened:
Apo: Speedboost (ok)
Deacon Armstrong: Speedboost with extra turn, AoE Def debuff (ok)
Ghostborn: A3 AoE Def debuff + Atk buff + attack (ok)
Sinesha on manual: A1, everybody on the opponent team dead. I win.
Sinesha with her great AI: A3, one opponent dead. Three opponents hit back, I lost.
Great, thank you Plarium.
