I have not pushed for a while, but I at times farm in Crystal and see replays from many high level team mates in high leagues.
To me, the problem is many are still fixated on pushing with Loonions & Hogs. Because they are effective and fast to cook.
But Disco Inferno mode allows Heroes, Golems & Dragons to have a far greater chance to breach a TH10 base. Pushers/higher league farmers need to either be more flexible with their pushing combinations, or be more selective.
