I'm not sure I agree. What was the skill in insta-killing players with bio as they thawed with no adverse consequences? Where was the fun in having it done to you? Where was the gameplay advantage of leaving this like it was?The only change is that you have to be a bit careful otherwise other players grouped with the one you insta-kill might thaw a bit faster (15% of the damage is converted to health). If you don't want it, don't group them. You can always move them apart. There are benefits in that....People said the same sort of thing about RFF (reverse friendly fire) where if you spam into teammates you get some damage. It's effectively the same thing.
