Weapons like the Nitronome and Polaris create incredibly disruptive explosion animations, making it difficult for the party to see enemy movements. Increasing the transparency or reducing the size of the animation would help greatly in this. As it is, these weapons are near useless in team play because they typically make the other party members unhappy.
I definitely agree with this. Nitronome + T3 Wolvers makes for sheer blindness and wild swinging until it stops. I doubt this really has to happen.
