"Tier 4 duo raids."

#PokemonGO: My partner and I have finally got to level 38 and have started getting maxed out Pokemon. We were wondering what tier 4 raids are possible duoable obviously with the correct teams. We both are getting as many machamps as we can both sitting on 3 maxchamps. This I’m pretty sure rules out ttar. We were both looking at trying to duo the weaker t4 raids and wondering if anyone has any pointers on what we need for them via /r/TheSilphRoad http://ift.tt/2Cqzknj
