After update 37, guass grenade no longer gets the pi damage from frostbitten enemies w hen applied by an allied ice tank or dps. Please fix as getting pi from other players is very fun and encourages good teamwork. I'm not sure if napalm grenade is affected, but gauss is confirmed not working both with ice tanks and ice dps
I just investigated this and it's definitely a bug. It looks like players / mobs were able to breakout of the Frostbitten state applied by a few Ice abilities. Thanks for the report! We'll get a fix out for this ASAP.
