"Level 10 gyms: take on the lowest defender multiple times, or pummel through?"

#PokemonGO: I'm always 100% down to conserve my potions/revives, but I'm not sure which is the better strategy. I've realized I can pummel well into level6-7/10 gym with my 1800-2000 team, but it's obviously very resource costly. Is it just better to just keep battling solely to the lowest defender at all times or to keep my current strategy of taking down as many as possible in one run? via /r/TheSilphRoad http://ift.tt/2ea0mDb
