I actually have a different issue but somewhat about hero set. I have my 3rd team as default team for PvE. Whenever I play the new quest for legendary hero tokens and switch back to regular quest, it switch my default back to the first team set up.
It happens twice already. I finished the first quest and went to play daily quest. My default team switch to the first one. I had to switch the team back to the 3rd one. Then I went to play the new quest again and went back to another regular quest, again the team switch back to the 1st team instead of what I have selected as the 3rd team.
Does anyone use a team rather than the first team for PvE?
