Three main differences between JWA and PoGo. First is the PvP battle arena. Second more supply stops around. And 3 bag space.
(1) In my case against JWA is the cost to level up your dinos which is too much. You need both coins and the respective dinos DNAs. This is the case if your mons are at L15 and above. You need to keep levelling up your dinos if you plan to battle in the higher arenas i.e. 6 and 7.
For PoGo the cost to level up your mons are stardust and candies. Players can collect stardust among others by catching any mons which are widely available. While candies can only be earned among others by catching the same mon or its evolutions. The maximum amount of stardust required to level up a mon to L40 is 10k. While the max amount of candies required to level up a mon from L39 to L40 is 12.
Best thing is both the stardust and candies are not sold in the store. So, the cost to level up your mons is technicaly free. On the other hand, in JWA coins and DNAs which are part of the cost to level up your dinos are sold in the store. This increases the tendency for players to spend real money just to level up your dinos to remain competitive. So JWA is more like a P2P rather than F2P - in particular when you reach L10 and your dinos are at L15 and above.
(2) While I like the idea of more supply stops, I came across that most were along the roadside and none can be found in malls. Which makes it hard for us to continue playing without disruptions to the darts supply - while waiting for your wife shopping… …
(3) As I have pointed out in my other post, the amount of darts that we could carry should be increased. 140 is just not enough - just adequate to hit 10 dinos on average. This is in contrast to PoGo where players can increase the items bag space significantly.
