I see. I haven't bought anything yet, though I'm sure I will later when I figure out what will help the most. Lucky eggs, maybe? It's been too hellishly hot out to walk around out there and hatch my eggs and when I tried on Saturday to grab a few pokestops when we went out to dinner, the servers were so slammed by everyone else doing the same thing, the game wouldn't even load properly.
So, I guess I'm just behind the curve. It makes me wonder what happens to people like me and others who might join later when all the training grounds are taken up by the veterans and faster players? Is it just a case of you can't play in the training grounds until you're up near max level? Or you have to spam all your pokemon and empty your inventory of potions? Ingress is kinda like that in that a level 1 person CAN take a portal of level 8 resonators if they're willing to spend a silly number of EMPs, but this gap seems wider. Or is there some strategy for fighting or healing pokemon that I'm missing? I haven't noticed them healing when I walk or over time.
