Too much gold+ need crystal shield generators+ $$$ heroes

The prices listed for hiring troops doesnt match up with the actual amount they cost, please fix this! I like the crystal shield generators in some of the story levels, and I want some fore my base. Please include these in your next update! The amount of orbs you need to upgrade a hero is way too high, please lower the orb cost for heroes.
