One feature in still has not been fixed that would vastly improve the experience. After 2 months of the game being in trainers' hands, the lackluster value of this one feature brings the question if it is even worth using.
With the issue involving one major element that most players will run into, players are expecting a reworking of what to do with the results.
There are plenty of features that gets right, but there are still some additions players want to see to improve the game. Trading is the big one, and it is part of the joys of trading card games in general. With being a newer game, it is unsurprising that something like this is currently left out of its early stages.
But as trading is a promised feature by the developers, it still may not fix everything frustrating about the game. Running into collecting duplicate cards is bound to happen when playing, as it is for any trading card game.
With all the duplicate cards accumulated by players from the variouspacks of, special promo cards, and the new set, there should be a better way to make use of these duplicates.
