What small changes could the devs make that would go a long way

Mine:

  1. Allow replies in clan chat
  2. Add a megadeck in the clan wars final round. Like, maybe when you finish in the top three you get to play a megadeck best of three (same deck each time)
  3. Reverse the exchange available on the offers page between gold and gems (use gold to buy gems)
  4. Make mmr and matchmaking fair instead of biased to enforce easy wins/losses by grouping deck “types”
