+1 for this suggestion.
This is simply a QoL change. DOESNT influence AT ALL the spawns / or if synch percentage. SImply indicates if u synched the poke or not. Allowing you to save up time on catching pokes, and releasing them. Its not a matter of pokeballs or w/e its a matter of saving time on catching a failure and having to release the synch fails after.
Doesnt impact at all how synchs work. The synch is still 50%. Only thing that changes is the amount of synch fails a person gets (since u wont be catching those).
Pokeball economy? Can only imagine one poke where that would be impactful: BELDUM. and lets be honest, this is just a QoL change. it wont be the other pokes where u use pokeballs (200$ ea) 20k u get 100 balls. its like 100 pokes. i dont see this impacting that much. PRO tends to hate to give some QoL changes.
But HEY, what about remove BMs then? This QoL also affects negatively the economy of pokeballs, and hunt. Ya if ur argument is this, i would suggest to remove Black MS from the game (btw Wally truly wishes to do it )
So overall, before arguing this impacts negatively XX, we already have some other broke features, this small Qol change wouldnt impact as much as you ppl are painting it. But thats my opinion.
