>>30181946Do you not understand how horde battles work or are you just really bad at math?
With ally chaining, you have a chance of finding the Pokémon you need, a chance of that Pokémon summoning an ally each turn, and you can only KO one Pokémon per turn. You get 36 EVs per Pokémon, meaning it takes at least 10 turns to max out two stats with Vitamins and 14 without, and that's not accounting for the time required to find the right Pokémon and the chance it will fail to summon an ally on any given turn.
With horde training in ORAS, you can trigger a horde 100% of the time, if you're in the right area it will be a horde that gives the desired EVs 100% of the time, and you can KO all five Pokémon in a single turn. You get 50 EVs per Pokémon, meaning it takes exactly 8 turns to max out two stats with Vitamins and 12 without.
Now I'm sure I don't have to fucking explain to you that 8 is smaller than 10, and that 100% is bigger than both the encounter rate of your target Pokémon and the rate of that Pokémon summoning an ally. Learn to fucking math.
