We did a small upgrade today: now the training rooms will prioritize your "leveling up" cards from your deck.
Meaning if you have 4 levelling up cards and 4 maxxed cards, the levelling up cards will ALWAYS be choosen in a training room (lost warehouse etc..).
Also, the wins / loss / draws are no longer recorded (popular request ) but the leaves, timeout and battle count are still recorded (to allow you to reach the 1000 battles star while levelling up).
Hope you'll like the changes.
Another suggestion: have damage of cards in the training rooms always reduced to 1 or even 0 or give ppl in those rooms like 30 life. The reason is that people still go crazy and KO me on turn 2 or 3 just because they dont want to wait for me to lvl all my cards since they have 1 or more fully evolved in their deck.
