If you have all relics, there is no reason to continue playing. Especially since they added ridiculous talismans to make characters literally unkillable (i just encountered a sentinel banshee which would just full heal when I gave her the killing blow and cleanse every heal block effect I casted no matter what) and op characters that recquire a specific character or a specific set of talismans to at least attempt to do something. The fact that you have to awaken characters to counter specific talisman sets like Labyrinth doesn't help at all.

Worst part is, you are forced to play PvP in order to get certain event achievements.

If gauntlet and dungeons had way less restrictive rules, it would be the only reason to keep me playing constantly. But, right now, I only connect daily just to farm trooper badges and dungeons whenever I can.
