Clan Wars Ideas and more - A few below
1. Clan War Rival Chat
To add a new level of flair/entertainment to clan wars. Players should have the ability to interact directly with the opponent clan. Maybe each player can get 4-5 messages per war and be able to trash talk a little bit after an attack. Wouldn't necessarily be catered to trash talking, but to celebrating wins/losses, adding more excitement after a close war, sportsmanship, and saying "good game" after a truly close, almost tied victory vs another clan. I think that this would add more activity during clan wars.
2. Mini Games / Daily or Weekly Base Challenge
During clashcon, there was a mini game that players could play where they could select certain troops to three star a base in the least amount of time possible. This would be a fun experience that could have its own leaderboard and could be reset daily. Supercell could draw the bases from an algorithm that randomly picks from a database of commonly used bases for different th levels. The troops and levels could be selected from data regarding the most successful attacks against bases of that th level.
Or maybe the bases wouldn't need to have a th level at all! During clashcon, supercell developers created bases that were troll bases, to say the least, with never ending clan castles and whatnot. Why not create a "challenge tower?" Where players go in and have an opportunity to try out a bunch of troll bases that increase in difficulty.
This is starting to sound like the goblin map, but hear me out. You could conquer one challenge tower and move to the next. The towers could be named after certain developers and it'd allow the players to interact with the devs in a new, and fun way. Beating each tower could reveal a secret hint to something that the devs are thinking about for the long term in clash. For example, beating the "lvl4" challenge tower reveals a hidden message.. "A new dark troop looms in the distance.. He/she has an electrifying personality..." (Chain lighting). I think that players would love to feel like they can uncover hidden secrets and easter eggs in this game as opposed to endlessly looting and fighting other players pvp. I think the single player mode could be enhanced dramatically in this way.
Let me know what you all think about these ideas. More to come!
