Engineer upgrade and others ideas!

To start I have this idea: how about an engineer upgrade? It's has to be a very expensive thing like 2000/5000 gems but would make the engineers work 20/25% faster every time. Our maybe you could put like 2/3 engineers working in the same construction making the upgrade time lower.

Second idea : SP should make a negative multiplier ( I don't know if are called like that) that would made archers and wall breakers more resistant to mortars strikes.

Third idea: More goblins levels! Or maybe restore the older ones, but I think it would be very cool if there were new level but WITH DARK ELIXIR!

Fourth: TH 11. I mean who never think about that? New defenses, more walls, ... Especially now that are so many players that are TH10 with all at max and they don't have nothing else to do in this game.

Fifth and last idea: How about daily rewards? I'm nobody to say what would be the rewards but I was thinking about maybe In the fist day like 30k of gold and elixir and 1k of dark and in the 7 day consecutive of playing you receive a gem bonus like 100/200 gems and so on ...

Hope you enjoy the ideas and comment please saying what you think about them :)

Ps: I'm not very good in English haha ;)
