Well, I do a lot of exalting. I have my Mire Flyer who can train
two dragons at once - I get them up to level 7 (sometimes 8 or 9,
but it's not really worth it), exalt, get new ones, rinse and
repeat.
You get around 10k for exalting a level 7 dragon. You can get adult
fodder at around 7-7.5k at the auction house, and it takes about 10
minutes to get them to level 7, so you can make roughly 6k profit
every 10 minutes, even more so if you breed your own fodder. After
a few hours, your hoard items (trinkets, materials) should also
make you treasure in the high tens of thousands. If you don't need
to use the food items for yourself, a full stack (99) of any Mire
food other than plants goes for around 12-18k treasure at the
AH.
It may sound daunting, but the numbers grow rather fast.
as I'm pretty inactive on here ( on pokeheroes ) I only really come
on to hang out with friends I'm looking to sell pretty much
everything I have on here for fr treasure or gems ( or will also
accept scatter scrolls, or bog or mirror breed change scrolls )
I have.. over 200 boxes and keys, a bunch of shinies , some mega
ables..
