Abuot EXP for team level, How you get them and where you see them, and one more tip
EXP is points you get, and you need them to raise the maximum limit of your team level
You get EXP for completing daily tasks, (write on the mission how much you get), and also you get them for wasting energy (equal to the energy you spent).
To see how much more EXP you need to advance to the next level, you can click on your avatar and see there, (see the pictures).
By the way, the jump between level 120 and level 130, is big, so level 130 is like level 155,
I'm so sorry I stopped getting EXP it was a serious mistake it stuck to my progress.
Tip: In my opinion, you need to first understand which heroes are good and which are not, and then go up to level 130 at top speed with only 5-7 heroes, your focus is only on them.
