Such a strange rant/ whine.

Why should your 500 Eden Verse gear give you a leg up in this content? It's like whining that you have to level your gear in deep dungeon, it's it's own content that's meant to challenge you in that zone/ instance. It's a level playing field where you're mean't to put in time and effort to make yourself stronger there.

Also they outright said that people who actively SPAWN the stuff will have priority over others. There's no reason to think 2 or more Critical Engagements or fates can't happen at the same time or around the same time so it's made to reward people actually trying to do stuff.
Aand the crying about tanks/ healers getting boned is non-sense. Lost actions are a form of horizontal progression like Logos before them. They can MAKE a tank/ healer deal way more dmg with lost actions or a DPS that can tank and hold aggro or cure or shield people.

ANNNND the big thing! Once you're in you can swap to any combat job and boom, you're lvl 80 with all your lvl 80 skills and stats you earned in this zone ... AND LEVEL IT THERE! That's cause there's no Deep Dng this expac and this seems soooo much better! You can actually play around with a job at max level to see if you like it in a zone where you're not one shotting and speed running and make progress with it. So if you don't feel like healing you can pick up your lvl 30 Bard and see how it feels at 80 as you grind.

They have learned sooo much from eureka and more.
