One of the biggest rumors floating around is that Supercell will add Quests to Clash of Clans. Either daily, weekly, or monthly quests. I'd love weekly quests.
Everyone expected Quests a few months ago, but we got Clan Games instead. And while they're similar, quests would be different. Similar to the single player goblin map and achievements but different. And no, I'm not talking about the "Gain 10 stars with Dragons" quests we get. I'm talking about real quests that are actually fun.
Before the end of 2018 Supercell finally added more levels to the Goblin Map. They're fun, but the most difficult one can be beaten by only using spells. Sigh.
Why not replace the Goblin Map with brand new Quests. Better yet, make these quests difficult to complete, and reward players with "Quest Jewels" or more league coins.
The image above is just a fan-made concept of quests and jewels, but it's something we would love to see come to Clash of Clans eventually. That said, all the League coins and additional things in the shop lately are a bit overwhelming. I don't see them adding yet another element to the game. It has to stay at least somewhat simple, ya know, for new players.
