New Building and New Hero

I do not know is this ideas are ruled out or already said just i said about my opinion.
New Building for TRADING TROOPS
Just like other games for an example like hayday(selling crops) selling troops for elixir
NEW HERO ABILITY TO CHANGE TARGET
A hero whose target such as defences,mines,storage can be setting up by user.This will helps alot and atleast we have a hero whose target can be controlled by us or else a new dark troop whose target can be set by player.
​Sorry if this is ruled out.
