Sister,
I can tell you that once you start running multiple Gladiators and even multiple stables, you spend a few hours playing the game. A good idea is reading alot on the arena results and see how others are fighting to get an idea how to set up your boys strategy. I will recommend spending a little cash and purchasing trophies then expanding your barracks. Multiple Gladiators earn you gold much faster, plus the more tavern fights gives you opportunity to find some good equipment. I have found a few blue level items on the job, and several green. But mostly you just find crap to sell.
