I like playing the guild wars because I get to compete against other players and not just the AI. But in my guild I am the only one participating. This is my second guild, I joined this one because someone there was participating but has stopped.
I have an idea to make the guild wars more attractive to players. The bonuses you buy with coins should transfer over to your cards just the same way the event bonuses last as long as the event lasts. Even the players that don’t want to participate in the guild war will want to spend the coins before they expire because they get a benefit on the Campaign or Duels or anything else.
More players interested in the guild wars would also make them more fun and dynamic and could be a game within the game. I think that was the intent of putting guild wars out there in the first place but it could use a nudge to make it worthwhile. Adding the coin benefits directly to the cards would make it worthwhile. This would also give aggressive players an incentive to buy coins, and maybe even create new aggressive players.
