So just experimented with this.
Only 1 hero with 5% pull chance. (Jibber)
10x pull no longer gives 5 gold chests.
Actually there are no gold chests with hero tokens.
Only bronze (60%) chest with drop health and energy pots, small exp. pots. and evo larva.
Silver chest (35%) drop health and energy pots. 100 exp pot. evos, and quick loot keys.
Evo monarchs are gone.
Out of 40 pulls I hit 1 Jibber (5 tokens) pull.
Hardly worth 100k gold for 10 pulls anymore for new folks starting out.
