There have been things I have done that you haven't. However I'm not going to rub it in your face like its some kind of achievement and prize since its a game. This is semi-the elitism I was talking about. Unfortunately for you I joined the game when Coils were already nerfed/done, so I really didn't enjoy them since honestly for 1 - you can't really get into a static that late in the game, and 2 - everyone who did them was honestly just disrespectful and thought themselves better then everyone else. I had a lot more fun just running easy zones like Crystal Tower. However your achievements are all dead now, that is no longer end game, your loot and entitlements are now the past.
I think a lot of skills might be changed to hopefully be raid wide to give more value to under-powered classes. Otherwise they will not have a place for some classes in an 8 man static.
This is why you design dungeons that you probably cannot beat in a single mention. The first boss of the dungeon is the easiest and it gets harder and harder until the end. Making it so you have a big raid dungeon and trash (which also has a chance to drop loot). Each named being further and further in the zone and harder. Most raids, might be able to pug and kill the first 3 nameds, however the other 6 might not be able to be killed in the same way. However at least people will still get upgrades.
TL;DR
Just fighting a single named is rather boring to me. I like zones with many named in them and each tier of the zone getting harder the deeper you get into the zone. Trash also should drop its own unique loot as well, so they are not pointless to kill.
Btw;
Crystal Tower was a lot more popular then Coils, pretty much everyone did them because they were fun, and didn't require so much being in sync. However I think they could still keep its popularity and pump up the difficulty.
