"Why is Dragon Tail + Hurricane not the best moveset for Dragonite?"

#PokemonGO: For attacking, if we look athttp://www.pokemongodb.net/2016/05/dragonite.htmlDragon Tail DPS w/ STAB: 17.1Hurricane DPS w/ STAB: 50.9would be the highest DPS. It is true too if we look at "Real DPS"http://ift.tt/2mUr4RP people would say Dragon Tail + Outrage is the best moveset -- maybe for defense??Still, for attacking, it seems that for attack, Dragon Tail + Hurricane is the best moveset for DPS. But even gamepress says best for attack is Dragon Breath + Dragon Claw.What actually is the best moveset for attack for Dragonite? And for defense?P.S. I just saw on YouTube somebody referred to this page:http://ift.tt/2mIukD1 moveset for Offense and Defense: Dragon Tail + Outrageoh well... why is that...? via /r/TheSilphRoad http://ift.tt/2msntgA
