New Goblin Idea

Ok so everyone remembers when we first got the game, and goblins attacked us with only 2 goblins, right? So I was thinking, wouldn't it be more of a challenge if we got attacked by the goblins more frequently? It doesn't have to be a daily thing, just completely random. The armies they attack with can also be random or fixed, doesn't matter. Let me know in the comments if this is a good idea. Thanks

hmm, I actually sorta like this idea, but they shouldn't be able to take out loot
