Question: Please define speedrun?

Why? Because you mention skipping packs of mobs and chests. I don't need a full grab all the mobs and pop hallowed pull but I also don't want to just stop and go every 3 enemy pack when it's extremely inefficient for me as the healer. If the DDs can get the DPS to drop things when there's 2 packs I fully support it. I don't want to go out of my way to hit a pack of 3 mobs that are guarding a trash chest. If you want the chest with x-ether/hi-elixir, ask me before you force me to spend time killing the mobs or healing the party. If it's out of the way, clear of enemies, you go get it. Or do it after the dungeon is complete. If there's no newbie, I'm not going to go out of my way to kill mobs that aren't required to be killed to complete the dungeon. If it's a low level dungeon, will always check with everyone if they want the exp.
