I have 2 personal ideeas to improve game ;)

1. In the Monster Lab to be Epic and Legendary cells with gold :)
   I don't say to be all time...its ok 1-2 times every week. For example Monday to be for a Epic and Sunday for a Legendary :)
2. In the next update to be next stuff :) A litle place in the game bar where to be an auto-play set :) With this if you activate it your food and gold is auto-colected :) We all know that not all players can go online every hour to put food and colect gold so...this set is in my opinion a good future update :)
   For 10 gems = 5 h
   30 gems = 10 h
   50 gems = 1 day

@Ulici-Sandu u know what i want thats a great idea

@Ulici-Sandu I like your first suggestion. The current Lab rotation is really getting stale, and the developers know this but don't update it regularly enough.

The 2nd suggestion I don't think will ever work, because the developers want you to log in every 4 hours to collect gold - for them, that is the whole point of the game (not fighting).
