Join my alliance : Holtz

just a newbie but try to be the best :-D
But i still confuse with battle system. When i attack Slinger with druid with same rank, but why my druid lose ? ._. can you explain about that ?
And if i offline for a hours, then when i see my city info. I see my gold/iron regen decrease to +1 ? Till i refresh the page or doing some activities ? Thats make me confuse and my gold not regen..
