There are players who cleared it at 6500+ CP, but you basically have to be a wizards who pulls insane, DPS out of nowhere to pull that off. For PUGs, even 7000 CP is a brutal struggle. The actual comfort zone is 7500+ CP. As I keep saying, this can always vary depending on your specific situation, patches, or server. But one thing is for damn sure unless your friend is an 8000 CP raid god, if you're under 6000 CP, just get the hell out and go back to Hard Mode. Gate 1 is a bit tricky too. The 195~190 bar mechanic is a tight time attack if you don't burst down the boss within the 1 minute 9 second time limit, it's a wipe. To make matters worse, you're fighting in a super cramped space, and every time you get hit by an attack, you get a 10% damage Nerf Debuff stack. If you get knocked back and hit the wall, you get slapped with 2 stacks instantly. At 7 stacks, you get levitated into the air and can't do anything. By 3~4 stacks, you’re basically dealing Low damage and failing to pull your own weight. For Gate 2, any party below 7500~8000 CP will have to do the Rumble mechanic twice. You cannot afford to mess up a single Just Guard (parry), you need to constantly chunk down the Stagger bar with non-stop DPS, and when you enter the first Rumble, you absolutely must reach Stage 3. For the second Rumble, just reaching Stage 2 is usually enough to secure the clear. (Of course, All members must finish the core mechanics very quickly and accurately. Because the Stagger bar only opens during the boss’s normal pattern.) Hard Mode experience doesn't really help all that much. The DPS check discrepancy between Hard and Nightmare is massive; Hard Mode gets cleared so easily that parties end up using completely different tactics.(There isn’t much difference in the boss’s attack patterns, but the DPS requirement is too high, it no longer shows the safe zone as before, and no mercy.) PUG parties are pure hell, but for static groups with high CP, once the members get completely used to the raid's attack patterns, it becomes a walk in the park.
