A long awaited update 1.3.20 is here, if you feel that game is now faster - it's not a quirky dream, some animations for transition screens were shortened. There are many balance changes and  tweaks, see it outlined below:

DUNGEON

•  Shows 5 opponets to attack
•  Better match-making, the same opponents should not cyclically return

CREATURE STORE

•  Long press the creature's icon (or fav within) to see where is used

IDOLS

• Mythic Idols now guarantee a 3 or 4 Dot Epic or Legendary Creature

QUESTING

•  You can now Quick Quest any map while in progress on a different Quest

There's also some ambiguous news, Essences are now color specific. This just delay bosses awakening but doesn't cut it nicely.

• Full list of Balance Changes
• Full list of all Tweaks

If you are about something wait, Kingdom mode should be behind the corner. Still no hints what it will be.

Please, update the game from the Store/Play.
