PvP system is really unfair and unbalacned. As a lvl 30 player, I got an opponent of lvl 280. In this stage of game (around lvl 30) it's not that easy to collect 5000 gold, and impossible to win. On the other hand my opponent can win easily, but seeing his cards, I don't think he really needed that gold pack. Withouth a proper PvP system, this gami is only a single player game, where your only task is to wait while you gather your energy.
