Trainer dungeon with the rations from log in doesn't really match up to starters dungeon. The 1mil and 2mil gold drop is nice if you get it but the exp cards is far too inconsistent, ranging from medium, large and super cards. They should have made it all super exps from at least the last stage.
Just hope next actual event provides us with another place to farm exp cause getting to Lv55 for inheriting requires a ridiculous amount of exp and this isn't doing it.
