Flareon wrecked by both Dragonite and Ttar and the second one often comes up in auto select and the first one often used, even by less knowledgeable players.
I think it's just to do with how many options there are to deal with Flareon, the two I've mentioned don't even get to the Rock/ground options or the waters, whereas for jolteon and Espeon you only really have a few options.
P. S.
Even for the immunity tier resistances, a 20 power volt switch or confusion becomes 10, and a 14 power fire spin also becomes 10, more or less. Therefore given similar attack stats, Jolt and Espeon are not at a disadvantage from a quick move perspective even when you consider the attacker running an immunity tier counter.
