Thinking of Quitting

I am now Team Level 105, most of my Heroes are 103. A have too much free energy that I cannot spend. I lack in everything basically to progress as before Level 100.

Problems:

1. Money: The usual money rewards are not helping much in leveling anymore
2. Skills Upgrade: Too expensive
3. Lack of Artifact (this progress stalled since 2-3 weeks already, maybe 1 per week for 5 heroes)
4. Emeralds: Too little for any progress, often spend on leveling (one every few days)
5. Campaign: Grants Team Exp, so I cannot do any Campaign.
6. Guild: Activity point getting lower per day (from 3000 to now 500)
7. Nothing to do

Since I do not dare to do a lot of campaign (and progress halts because I cannot upgrade hero levels), only usual daily activity remains that grants little things.

Equipment: Here I still see some progress because it doesn't need
Skins: Today I got only 10x10 extra Chest and Outland -> around 2-3 Skin levels per week (per proper hero)

Right now I go into suspense mode, i.e. I play only on weekends. Let's see if anything improves. I know very well that weekends often have less activity, but some events at least run until end of week.

Not sure if I still should do Nightfall event. Seems like a waste of time.

I'm so disappointed about high level progress. Was looking forward to it, and now.. pure boredom.
