With a guild like yours, you could make a project to go through every single quest in the game, and make a note for each of them if they have a certain mechanic that could be used for an exploit. That way you would be able to find every possible exploit to do with quests. Being close to loremaster myself, i'd say you can do at least 30 quests an hour. You wouldn't have to try exploits every quest, just note down if there is a vehicle or a cut scene or a certain buff etc. and then go back afterwards to find the exploits. If organized properly, a group of 20 people could have this done by the end of the week (player 1 does x zones, player 2 does y zones) and so on, using wowhead as a guide.
Just a suggestion ofc, good luck finding more methods
