Training a full, high power army with spells and heros, is what will be needed to make attacking worthwhile now. These armies take a LONG time to train without boosting, on the order of hours just for spells and high level hero recovery times.
Long gone are the days of 15min training times for armies, UNLESS YOU BOOST WITH GEMS.....
So yea, this feels like it is about giving players even more reason to use gems.
