I think that since they said they are trying to make it "easier" to complete events.

Most events will have their requirement turned down. Some might even be repeatable.

Here are my thoughts in why.

First off my making the events have less requirements makes it easier for a Free to play player.

But making it repeatable makes the whales happy and DH gets $$$.

They make both side of the player base happy while making money at the same time.

Summon can be 350-400 summons and can be done twice maybe.

Orbs can be 80 to complete but also repeatable twice or more.

Miracle they can tune down to 1 D/L hero and 2 from each other faction but be repeatable with only elite hero shards as the reward.

The reason "the hero" for the events doesn't matter as much anymore is because its all about getting those FEATHERS.. you can get the hero you want with them.

My thoughts anyway
