I've played for two years now. At times the game pace will slow down but eventually new content will pick things up. The summon rates are very generous. Update: Game has become overly complex thanks to powercreep and several modes with a score based ranking system that requires making teams with pay2win units. I no longer look at new units or feel interested in them. Update:I've played for 4 years now. The previous issues have only atrophied.
