I think the game would be more interesting if it has some improvement like below:
1. Test your Metal should be added to a new play mode (everyone can play at any moment, not a temporary event)
2. Domination or Breach mode should have a AI level selection. (LV1 AI is really boring, no skill practice no challenge, just a waste of time I think)
3. Top level of hero should be lifted to a higher level in every season or every year. (e.g. Y4S2: 70→80)
4.The record data should be counted separately in PvP and PvE to make much more players participate PvP more actively.
