In the Cold War strike, final boss has a mechanic that makes a player deal damage to everyone around themselfs upon hitting the boss every 2 seconds. With players stacking, this creates a massive downed/revive fest. I can see this mechanic create a very interesting fight, making ppl keep distance a bit, and not stack, and I believe this was the intention. Problem is that there is near to no punishment for getting downed, everyone can super easily revive you.
I think if a new mechanic was added, that created some form of punishment for getting downed during this boss phase, for example getting some longer lasting debuff, or any other form of punishment, it would insetify more tactics from the teams, and make for a much more interesting boss fight.
