Yes, some individuals wants all easy and complain about everything instead to get focus in the basic. Sure I do not blame many because grinding it is not easy and take a million of years to progress in particular when the base was activated.
I started with my niece and we got focus in the basic of grinding together next to each other then we started to understand how to grind better but everyone play as they want or play according their limitations in real life and thinking that the majority of players are minors and school students and depend of parenting it is the time allowed to play etc.
Yes, if no money so no other way than to grind and look for best how to do it per player.
Grinding help level up fater getting some more slots at garage space, energy bars, gold and extras.
I still doing the same basic of farming to progress every item and all had been advanced in that way no using tokens for it. Sure some item purchases.
