I don't know if many have suggestions about the guild chamber invaders, but i have thinked a little about it...could you instead of contribution change it to bounded balens instead when they are killed 
3 invaders to get some contribution is not that intresting I guess and maybe have some diffrent level in those 3 and diffrent amount of reward
I remember back in time it was like a fight to get those invaders, now they are always left and no one is intrested to kill it because it's easy to get gold
Oh one more thing when i already talk about the guild chamber..
It should be great if it worked to battle the guild members in the chamber again like before
I like activity in all places in the game
Just a suggestion nothing else
