Since update of July game has become impossible for new players, cant get good cards till you get some decent ranking and can't get decent ranking without decent cards or gold to buy them, and quests now require you to use all kinds of cards, which as newcomer.. you do not have. This update just shows developers are in it for cash grab, or just incredibly dumb for not noticing newcomers can only play if they pay
Best tip a old player can give new people. DO NOT JOIN AT THIS CURRENT TIME!!
Most things are broken, things you really need. Things in this game that are "coming soon" have been for over a year, and since than more stuff broke than got fixed or added. What got added is more super awesome discount sales where they overcharge you a ton. And as things are currently looking that might soon be your only way to even get started.
If you do join, i wish you the best of luck, and advise you to ask in chat for help and tips as the developers will ignore you completely, the players tend to be quite nice and some very helpful.
