I must say this is a great game my one complaint is that the final achievement reward (semblance anvils sold in the achievement shop for 2000) is slightly anticlimactic.
okay we need to take down all the comments on how the final upgrade is impossible and to put up an impossible badge that comes with an auto ban for getting the final upgrade to catch hackers
Instead of revamping the energy system why not just have arena battles give gold and exp as well? progress in the story would be limited but not playtime while getting rewards.
I accidentally clicked on the buy a card with warbonds button beacuse the daily reward wouldn't go away. I am willing to exchange said card for my 20 warbonds back.
