Hey, why don't you think of making a building that unlocks at town hall level5 costing 250000elixir and 250000gold,that enables us to but troops from barracks using gold instead of elixir (enables us to choose)..
And heroes..we have land heroes..but ehy not make a flying hero ? A drahon leader ? That leads dragons..ability (active always): not effected by xbows and inferno towers.that'd be so cool,wish you appreciate that and make the best you can to make it work
