Why is Flareon such an unpopular generalist attacker? It is one of the highest neutral DPS mons in PoGo, is great against DG Blisseys, and resists fairy attacks which the big 3 gym attackers (Tyranitar, Dragonite, Machamp) are all weak to.
Also, although most of the big 7 resist fire, gyms are no longer comprised of just the big 7 now with the CP sorting removed, and the limit of 1 Pokemon per species per gym. "Fire is not relevant in meta" isn't an excuse now.
It is also the fastest neutral DPS Eeveelution, but for some reason many people prefer Espeon for a glass cannon generalist despite having lower defense and slightly lower attack.
Moltres' attack is only 5 higher than Flareon's. Eevees and their candies are so much easier to come by than Moltres. Eevees can also be caught at high level, while Moltres can only be caught at level 20. Using a charge TM on Moltres might cause jumping between Heat Wave and Fireblast, but for Flareon, both Flamethrower and Overheat are great moves. "Moltres is much better" isn't an excuse.
Or are people not using Flareon because it was rather useless in the main games? I hope this isn't the case.
