They can sort this if their intention was to provide players with damage boost buff as a seasonal theme.
They can simply remove all the environmental annoying visual effects and add a fixed damage boost x every 90 sec. ( that does NOT stack!!!).
The icon shows when the player obtains it for 7 to 10 sec duration which occurs once every 90 sec.
I dunno if it’s already late to adjust the seasonal theme by now … all I know is the game was not prepared for a broken mechanic visually as well as been abused in multiplayer game play by maintaining the damage boost buff more than what its intended for. They should have a backup seasonal theme plan if such a mess happen to apply in emergency situations.
