To be honest, I'm not buying the gems without any suggestion. anyway, i'm on the townhall 8. already upgraded some of the stuffs. and i have 500 gems on my hand. completed 40 achievements out of 66. these days i'm so into this game.
1) should i get the 5th builder now at this stage?
2) as am on the th8 is it good to have it now?
3) if not, can i use my gems on the laboratory?
