I've been getting the 25% luck elixir often and use it on Ydra Rooks Hideout. It takes about 3mins to get to mother and kill her which means I can run several times in the 30min block. Since I'm only at L25 (and staying here for now) I'm wondering if there is a better place to run? Is there a boss that might take longer but gives better loot, or somewhere with 2 bosses nearby, etc?

Thanks

Feel free to discuss higher levels but post what level you need then.
