I honestly feel only two things need to change in Vespers, and neither of them involve the hp of the bosses. Starting with the servitor boss. The amount of time you get for DPS is way too short without meta loadouts, especially if someone gets killed by any of the bosses attacks while you're trying to drop the clone. My recommendation for this encounter would be to change the DPS timer formula. Make it so you can gather more than just two sets of numbers if you want more time for DPS, let's say five seconds per set of numbers input. So if you punch in two sets, or four numbers, you get ten seconds of DPS. But if you punch in five sets of numbers, or all ten digits from 0 to 9, you get 25 seconds of DPS. Plenty of time for a one phase. Moving onto the final boss, the only thing I would like to see changed in this encounter, are the benefits of killing the clones that spawn during DPS. Aside from getting them to stop shooting/chasing you across the arena while you're busy with trying to get in as much damage as possible, all while dodging the lightning strikes, killing clones gives zero benefit to you, aside from that one clone holding the bomb to extend DPS. What I would change here, is giving a beneficial reason for killing the clones in the DPS arena. Every time you kill a clone, you gain one stack of an Ark damage resistance buff that lasts for ten seconds per stack, which also applies to the lightning. If you're rocking tier 10 resilience with this buff active, you can survive a direct lightning strike with a small amount of health remaining, though the AOE field will likely finish you off if you don't move away. But at the maximum of three stacks, you'll have more than half of your shield remaining, and the aoe field will only tickle you from then on. But you have to keep taking time away from DPS to killing the clones to keep the buff active, while also trying to share the buff with your allies on top of that. Adding to the chaos of this phase, while giving players a way to survive the lightning.

It's Spire of the Watcher all over again. This is why I stopped buying Dungeons. Spongy bosses and awful RNG.

There’s nothing to adjust. Stop asking for a handout and get better. Learn to move around the map and strike accordingly. Take out the decoys when you can since they have no health. The damage phase is EXTREMELY generous Also, the meatball in warlords has just about the same amount of health as Atraks, so that was false info you just gave
