(Disclaimer: This is my personal opinion & nothing more, be nice to one another) My worst to best list would be something like this based on accessibility, also yes this is also partly a post on why I think EOW is an amazing raid for new comers. - Spire Of Stars (Hated it, always will hate it for how tricky it can be to get new comers to understand the mechanics, people have vowed to never raid again thanks to this one) - Leviathan (Too many puzzles, not enough bosses, till fun to always run it just low for the lack of bosses) - Crota's End - Very easy ones compared to the other raids but is filled with so many fun nostalgic moments, again that lamp section is the shiz !! - Scourge Of The Past - Sparrow racing can be both annoying and fun, the boss fight is fun but this gets lower on the list for being a smaller raid - Last Wish - This raid is a beauty, not just for the size and scope but also for the variety in it's encounters. Kali/Shuro-Chi/Morgeth/Riven each a wonderfully constructed puzzle easy to get into but tough to master. The vault is the reason this falls a few points below for me, that puzzle section walks a thin line between challenging and annoying. Fun when it works but doesn't work all the time if you are running it with new people. Also Riven is probably the second best final raid boss in game. - Wrath Of The Machine - Again an amazing raid but a tough nut to crack for first timers. I know challenge is a thing but I always give points for accessibility, a challenge which can be easy to learn but tough to master is what I love, wrath is half way there. (atleast for me). Also this raid is the most fun when you run it with a group of friends. - King's Fall - The grand daddy of all raids, I still remember the first time we stepped foot into this one, the sheer number of possibilities from secrets everywhere to the atmosphere of the raid itself and that encounter with Oryx i still gape in awe every time I play it. One of the greatest achievements of Bungie Raid Design. - Vault Of Glass - The second best raid on this list simply because of nostalgia (yup I still love it) and there is something about this raid that just clicks, from the final boss to the lore behind it to the right difficulty VOG is a timeless masterpiece (literally) - Eater Of Worlds - Well here we are finally, remember that word accessibility, yeah the only reason Eater Of Worlds is so high up the list is because of it. Have you ever had to bring in a complete stranger to raids into this encounter, teach them the mechanics, watch them slowly see the thread unwind, get the hang of it and become better at it progressively ? I have, I consider this to be the best example of how a raid should be easy to understand but tough to master,Let's talk mechanics the final boss phase in itself is split into two first you are to break down the barrier around the boss and then the second is to DPS the boss. But the brilliance of this encounter is letting you learn the elemental rotations, charging of craniums and shooting the appropriate element with the charged cranium, all of this happens in the final encounter and the encounter before that does such a wonderful job of setting the stage of what to expect, funny as it is for something so simple once you understand it but what would you do if there were three arc mines ? it gives you challenges but you also see team co-ordination happen. the runners from each side immediately jump up to the work and say hey i can bring an extra one to charge up. Let's not forget there are 2 specified roles, clear adds be a runner and this is shared between three plates meaning if there is trouble on one side the other runner can jump in to help, I cannot remember how many times we had this insane save at the end because we were able to co-ordinate in time. The boss itself is also a gem, you are given a brief window to do damage, and while the boss does it's best to screw it up with those nets and harpies blowing up the trickier part is to avoid wipe, from doing 4 stage argos where we barely had time to kill him to wiping argos one phase I have seen it all. All of it is possible and this growth of the player is what makes it possible to be able to get into the raid understand the mechanics and become a master at it.There is nothing quite like it, the feel of collective success and the sheer thrill of doing it all over again. Kudos Bungie, please give us more EOW style raids with the length of Last Wish/King's Fall and that would be my gold standard for raids ^_^
