I'm one of the people who has cleared the extremes but not savage.

Up to this point I was more likely to ignore high-level content and spend my time levelling my alts, but the graphics update and style shift has made most of my characters "not themselves" so I've shelved them until (if and when) the models get fixed.

The Valigarmanda weapons were cool so I wanted to learn that fight.

I might not have bothered with Everkeep as I didn't like the jewellery that drops from it, but I accidentally signed up to the wrong party one time and ended up there, and the group encouraged me to stay and learn the fight. Now I'm willing to jump in if I see there's a party struggling to attract members.

Savage, on the other hand... I didn't like any of the outfit pieces on offer so I didn't even bother unlocking it. I had kinda-sorta plans to at least take one of my alts through Dawntrail who would better suit the gear style and the mount, but never got around to it due to a mix of busy IRL and being put off by how much my character doesn't look like himself right now.

So, yeah. If it wasn't for the second character I might have tried savage on my main for the sake of it, but it seemed like double effort to do that and all the gearing up if I was going to do it again on my alt, but then I didn't actually get around to doing it on my alt.

Gearing-wise I'd rather putter along in my mix of raid/tome/dungeon gear than worry about being best-in-slot.
