I'm extremely disappointed in the direction this game is headed. With the recent dragon upgrade update, Tap4Fun shows how much they disrespect everybody's time. To go from being able to use 30 upgrades worth of dragon stones to 2 in one update is something the devs fail to understand and justify it with "We removed the castle level restrictions and gold costs", without seeing how it impacts the progression of players that eventually get to said castle levels and accumulate enough gold.
