I'm playing the game because I want to complete my Pokedex (or at least catch as much I can). I only fight gyms because it gives me coins to buy more incubators, which leads to getting more Pokemon from eggs. *I only take over easy gyms though, I find it really tedious fighting for more than 5 minutes and don't have the Potions for it anyway. I hope they bring out Pokecentres that can heal all your Pokemon at once.*
