Cards sell for way too little. Buying a homeworld pack costs 60,000 gold, and selling all the cards you get (assuming no legendaries), will only give you 210 gold. That's almost three hundred times less than the buy price. A higher sell price, or a trading system (like turning in a card for a random one in the same pack 1 rarity down) would be much appreciated.
Deck upgrade gives you another deck slot to edit. If you have 6 decks, and buy another one, it gives you another place to arrange and save cards. Only saves a little bit of time.
I am only level 18, but I play at least once, often twice a day. I am looking for a faction to join. Does any one here know of or lead a faction that is just starting out?
You could claim that Mardek was ripped off of Final Fantasy just as easily as you could claim that Skyrim was ripped off Mardek. ITS CALLED A FANTASY RPG!!!
the energy system, while annoying, makes it so losing a mission actually hurts a player. Otherwise, players could set auto 4x speed and beat every mission in game in 2 hours without having to make a good deck. The energy is annoying though. It would be better only to lose energy if you lose a battle, so you are rewarded for correct strategic decisions.
