OKay so the latest update added the "opt in/out", thats awesome. But the clan perks were really uninspired: all tied to war and only 2 perks with increasing effect.
Add more campaigns to the game, both single and clan based. All of the emphasis is now on wars- I'd have loved to see perks related to things in normal gameplay such as total resources farmed by the clan, donations made, 1 million goblins used (being creative), but there are so many options to help make clans more exciting outside of wars! And I'm saying that as someone who loves to war!
