Boss effects loading mid-fight, GGG rushing new content for PoE1 instead of fixing PoE2

Not only that, but the fact that bosses spam invincibility phases over and over with no cooldown is just ridiculous. Today, Viper Napuatzi pulled off Arakali's Sting phase 3 times in a row without even fighting me. The boss flies for a full minute and her invincible army tries to stab me with poison. I know the game is at the beta stage but things like that shouldn't take much time to fix or balance for a development team that big.
