I gave up on the game after reaching the to level and leveling my base. I score around 6k in a war and 11k on dedicated weekends.
It feels very samey after a while, and the dedication to the team is too restrictive for me at that level (i have a little one, that deserves my attention).
The character random draws annoy me as there is no guarantee that you wont receive dupes.
I have swapped over to Final Fantasy Mobius for my game grinding needs, better loot system, less commitment.
