Step 1. Dont remove capture milestones.
Step 2. Find another way to make players enjoy the game without creating new account. Like Making new Overworld Milestones that are harder and keep them focused on doing them.
Step 3. Dont create boring Daily quest game. I just had to enter T0 map against my will so i can be #Competetive against other players who farm airdrop points. This is ridiculous! Why is this happening? Is this how ppl will show their "SKILL" by wining 6 fights in T0 and capturing 6 monsters in T1? Or Shooting at annoying Bees?
#Suggestion. Not to kill the hype from Overworld.

Milestones were good
As @proud zinc said, it makes the difference between free and paying players
