@amulmuzz You are a cup half empty kind of guy aren't you. You don't lose any energy by leveling when you have a lot of energy in reserve, you just gain less. What's next? Are you going to suggest that because gold packs can be paid for in dragon coins that they should drop the best cards?
To make titan an easy kill wait for him to attack then put a tower between his legs. He'll attack it, but he won't be able to hit it. As long as his minions don't kill the tower he's stuck for your archers/mages/spells to kill.
I don't mind that this isn't the full game, what I do mind is that you blatently mislead the players. You say it "includes the all the functionality of a full PC version of the game" yet it doesn't have multiplayer or the full campaign... how is that all the functionality?
