Difficulty of normal content.

[Infindox]

Actually, we had new content in EW, besides the old Eureka/Bozja grind. But Criterion was a failure, difficult content ? Yes. Engaging and interesting ? No. Rewards were lame, fights in themselves weren't interesting. You clear them to get the mount, and pretty never much want to see them again. They admitted themselves that the content wasn't good enough in what it tried to achieve.

Alliance raids design was also a failure (Halone was fine tho). When you enter an Alliance raids, you're expecting mechanics around team A, B and C. That was not the case in EW.

Also, half room AoE designs got boring really quickly.

Island sanctuary depends on personal preference so it's w/e.

Criterion failed for me because after I did the normal mode, there wasn't much reason to even try or do the harder modes because I could just buy the mount on the MB and the weapon skins were not that great. The "hard" mode was doable by most but the Savage version was sometimes even harder then some actual Savage fights, so most people won't bother.
Also yeah, the EW alliance raids were a bit of a face roll. I *don't* want the DT raids to be like Puppet's Bunker (too much downtime with the NPCs talking and the raid takes forever) but I would like to see some more mechanics with the ability to screw over teams if they don't do it right.
