That monthly pass thingy
So I've been playing the game a while and I've spent a total of $70 on this game. I also have over 1000 matches so I think it was worth. I've spent more money on AAA games to play half as much.
But I think a bit of consumer advice here will go a long way. If you do have $15, I would say get the monthly pass. It's way more effective at obtaining cards than saving your gems to open packs. It's way more effective at leveling units. This might get that pack nerfed...but I have everything. That $70 I spent, $60 of it was that monthly pass twice. I now no longer feel the need to spend any money at all.
Food for thought.
