Valus Ta’aurc says...”hold my beer.” We’ve seen that a bullet sponge is not the answer. But, like you, I absolutely hate the three phase boss encounters that seem to be the rule and not the exception. I feel like it ruins the flow. I won’t get started on the half a map AoE stomp attacks. Perhaps a solution would be to add an elemental shield to the boss. Sepiks gets a void shield. You knock it down and then he takes damage. You stop doing damage the shield comes back. Your team has to decide to prioritize boss damage or add control. The wrathborn hunts worked like that. I know there are ways around it and I could smoke a wrathborn boss in a few seconds with Anarchy. But it was better than the current strike mechanic (IMO).
