I can't say it enough: when speed running became so popular, we were i90-100s running i55 content. Current expert dungeons are i80. Things. Hit. Back. At least now they do. And no amount of High Allagan/Ironworks/Dreadwyrm gear can make up for more damage coming in vs casting times and healing potencies. Big pulls just aren't as practical anymore when you consider those factors, and last I knew, wiping a lot - if at all - doesn't sound like it's part of the speed run description.
