I feel that the game becomes infinitely more fun if you utilize the entire map in boss encounters. PoE objectives is a good step to make fire teams do that. I'm going to rant about each strike boss and why I think moving makes it better (and why it is impossible on some strikes) and some mechanics I feel could be cool to put in place for the fight. Devils Lair: The area is a little small to move in, but not impossible. Sepiks teleports promoting movement and has long range and close range moves. I thinks Devils lair is actually relatively well designed. Summoning pits: Phogoth's area is great in terms of size, but any strike with a burn requires you to camp, plus the adds that span are oppressive. As for Phogoth he has little to no real mechanics outside of being a bullet sponge. I think adds should be lower in number, but at 75%,50%,25% hp, 1, 2,3 special "summoner" wizards should spawn and restore health if not killed in a time limit. Phogoths base health should be reduced to compensate. Archon Priest: the Archon priest area is great to move around in, and I personally love jumping and sprinting through the area. Sadly the only mechanic is huge waves of adds. I think the Archon Priest needs a special move or mechanic- for example, a ether machine spawns granting a shield. If the machine isn't broken in time the boss removes all guardian shields for 15/20 seconds. The machine could spawn at 90%,60%,30% health. This would make burn strategies impossible but be a simple mechanic to play around. Nexus Mind: The Nexus mind room is large enough for running around in but it's only a circle as the boss is always in the center. Sekerion is a bullet sponge. A cool mechanic could be changing the room slightly (it is terraforming Venus after all) and moving pillars to new places, and causing random rubble to fall killing camping guardians. Cerberus Vae: Valus Tauruc is a huge bullet sponge with no real mechanics. He needs his health lowered slightly, or a new mechanic. Mechanic wise I would suggest that unique phalanxes (rising lieutenants) spawn. Killing these unique phalanxes would do 2 things- first this would "enrage" Valus- he would now use an upraded missile that fires at 2 guardians, and his chain gun would function similar to the devil walkers main cannon. Second Valus would enter a panic state if he does not kill any guardians in 10/15 seconds, triggering his walk across the room. While panicked Valus would take 300% more ability damage (super/ grenades/ melee) and will only attack with a debuffed version of his normal rockets. The rockets would move slower and fire less. Psion Flayers: the psion Flayers is a decent enough fight, the triple bosses are unique and the adds not to oppressive and the room is nice. I really like this strike. I will post my thoughts on other strike bosses in the future. Thanks for reading.
