Regarding yet again... more nerfs.

[Galactimus]

I don't get why they are nerfing these things

This content is 3-6 months old. SE has determined that a lot of players are still having difficulty with these instances. Due to our item level being increased to 110-115 these nerfed instances no longer hold as much value to end-game progression as they once did. A nerf is perfectly acceptable considering that players are forced to kill Twintania and Titan (Extreme) if they want to play half of the new content coming out. Besides, the fights may be easier but people still have to learn the mechanics.

I hate nerfs. I wanted to clear this content without the nerfs

The Coil echo buff can be removed (Yoshi already stated this.) The echo buff on everything else only applies if your party tries their hardest for three minutes and end up wiping. Therefore, you can still complete every single one of these instances without the Echo buff. You just have to not fail on your first attempts.
