Rural Area here, out of the known players (which covers almost every player here) we have:
- 6 Mystic
- 18 Instinct
- 20 Valor
All spoofer accounts we've noticed in our area quitted to annoy us in the last 4 months
Even if Valor and Instinct are pretty even, Valor is more aggressive when it comes to gyms (mainly 2 people), but all in all, no one really GRBs much and Snorlax/Blissey/Chansey are not too common in gyms.
I (Mystic) can sweep through most gyms without even using Dynamic Punch, since people usually throw in trash
There is no real rivalry here, just some people who have more fun battling gyms than others
