Possibly, since technically it's an exploit. However that said many see it as a way of giving the smaller players the opportunity to advance further in Palace then they would have with full formation statues.
Morgan, I don't think that's how the devs envisioned Heaven's Palace to be.
If Heaven's Palace were full of 1 hero formations, what would be the point of it all. It would just be free cards and medals for everyone. There would be no challenge at all.
