As far as I can tell, once the entire line of nemesis monsters are out then you can essentially say it is a waste of time to rank up anything else.
The time it would take to rank any monster from the team shop, the monster will be obsolete by the time that happens for even a single one. AT 2500 coins and our team makes like 6k in 90 days so can look forward to another year and a half.
I had bought a zyla and kaith, but likely never get one of them to even lv120......
I could save up for 6 months and get enough gems to rank a new monster to 130, but now with nemesis it basically made legendary monsters obsolete.
I almost can do dungeons due to the over leveled nemesis monsters I am forced to face in the them, and it only seems to be getting worse.
The cards seem really stacked against me, what am I suppose to be doing? Where is the goal?
