I spend currently playing every night ne good hour of this game. The crystals that you can buy more, you also get paid plenty or achievements. One can also get quite a lot of good heroes and so if it is done properly, you can keep up on its level well. Of the daily Hrausforderungen I manage almost always more than half (yes, some are unfair with over 10 lvl on a but heck?). Who has fun with it his tactical skills always try again and has no problem with LVL farms, is the right place.
