There are some cool puzzles in the game, but unless you have a group who is all doing it for the first time (and don't mind failing if you get it wrong, some of them are timed or only give you so many tries) you usually don't end up actually doing them. I managed to get in a few groups like that and had fun, but mostly it was just repeaters who were only after the loot and didn't bother with the journey.
Maybe I was with a bad guild, but most of the big raids we went on were rather boring. Move here, kill baddie X. Move there, kill baddie Y. Repeat a bit. Wait there until Soandso finishes with puzzle Z. Move and kill something else, or collect some treasure. Rinse and repeat 500x until you get lucky and find the special item you want (I never bothered, which meant my char was poorly equipped, but I got by). Unless you were actively looking around (which was discouraged in most places, since they wanted you to stand still and not draw mobs) you never even got to know the place other than the shortest most efficient route that they were taking you along, and any puzzles were done by people who had done them 1000x before or had read spoilers for them since the group didn't want to miss their treasure because some new guy got the puzzle wrong.
