Yeah I'm not sure this stacks up too well with all the other stuff you can do with a team. Those elixirs are quite useful for leveling but have found the drop rate abysmal. Now that you can buy the lvl 100 versions, it just is a waste of time in the long run 'for me'. Farming medallions of the legion is some of the easiest gold you'll make this expac! For steady hourly gold- some people use LFR to farm Heart of Fear up to the first boss with treasure pots.

But thanks for sharing though. Always good to get out there and try something different!
