Mistake in Attacker List
In Moltres section Fire Spin/ Flamethrower is stated as a great set, but Flamethrower is imposible to get in Moltres, aside of that I think Moltres surpass Entei in most matches as an attacker since its DPS it’s not sightly higher but considerably higher, so it’s usefulness as a generalist is better, with Flamethrower you sweep weakened gyms but in that case you can use something better like D’Nite or Alakazam, seriously you put Entei over Moltres? Considering Flareon has higher attack stat and the same ms, I think it can be better when you need a high damage dealing attacker, longer battle time doesn’t give him (Entei) a better role since you don’t use Fire type against almost nothing but as a high DPS generalist

And where does it say Pokemon are listed from left to right in descending order of effectiveness?
Even if it were the case the list is meaningless for non casual players as gyms are easy to sweep regardless of what you have or what's in it.
If you just want justification for powering up a Moltres changing a list isn't going to do anything to it's actual effectiveness in game.
As for it having "considerably" higher DPS, a 6% increase in attack is hardly a considerable increase.
