Guys, The problem is there is no content for large ZVZ forces right now, So in return you are seeing theses large zvz forces attack hideouts because well there isn't anything else for them to do yet, If its still a major problem after the season starts and after they make the changes they already said they are making then we can talk about more option to fix the problem for small guilds.
If large guilds are going to crunch the hideouts of small guilds during off-seasons, then it's possible they'll do so next offseason (especially since territories usually remain owned during offseasons). If so, that's a problem.
I don't know what the other "big" alliances are doing, but we're only killing the hideouts of small guilds that are in our way. Every time we've destroyed one of these hideouts, not even a single person has walked outside to even see what's going on, much less attempt a defense.
You can kill hideouts that are enterable? I thought that was only possible during the first bugged wave of hideouts.
Anyhow, I'd assume that the defenders were in a nearby dungeon, saw the size of your blob (assuming you had one), and decided to not throw good money after bad.
