This KVKR event is stupid. And the reward for winning is not worth playing for. There are thousands of players in the kingdom and the most level 7 tiles I have ever counted at one time is 24. I am telling my clan to shield up and take a vacation for these boring 3 days.
Come on Plarium. No one wants this for 3 days. And make the reward valuable. A hundred Level 7 tiles and spread them out more, Extend them as far as the level 6 invaders go. In fact, make it easy on yourselves, Just replace all level 6 tiles with 7's.
2 day event and at least 100 level 7 tiles at a time and I will go back to playing this event. And give 2 days between events. After a hard fought battle we need time to heal, train and collect res.
