Hero Idea+New Mine

1st Of All I think that the Barbarian king and archer queen look a bit bland. My idea would be if the heroes costumes changed as the Heroes level up just think having a level 10 archer queen or barbarian queen having that same costume as a normal archer or barbarian would have at level 1 and when the hero levels up ten or so levels so that its costume match the one of the troup it spawns. (Hopefully this makes sense)
2nd a gem generater drill/collector I think that it should cost the maximum amount of gold and elexir you can get a th11 you should only be aloud 1 and I will generate 1 gem per hour this will be useful for people on th11 max out there bases easier. I know that this might sound really op but it would be very useful because it may take many months to max out a th11 base
