yeah! I can understand that "one-click-fight" is kinda boring, but this is definitely too much. Spending 40 min just to get 400 gold and 4 Common chests? That's not really enjoyable,..
For me shortest fight so far was 2.5 min, longest 12 min, but mostly its around 8 min.
Now, to complete " Get 500 gold", " Get 1200 gold", " Get 4800 gold", " Get 6400 gold" quests will take about 40min, 2 hours, 8 hours, 12 hours of constant grind accordingly! Which make Event Mythic card unreachable completely! You NEEED to SCALE rewards at least 5 TIMES !
And good luck to guys who trying to reach DL...
