Am I useful now that I finally can learn Flare Blitz?
Well, I’d say you’re arguably no longer the worst of your siblings, which is… something, right? Your offensive movepool is still really bad, and that’s a problem that pretty much your entire family struggles with. The best moves you all share are support techniques, so it’s your toughest siblings – Vaporeon, Umbreon and Sylveon – who are the most consistently useful. Espeon gets a leg up from her ludicrous hidden ability, and Jolteon kinda gets by on his good offensive stat distribution and strong attack type. Leafeon is pretty bad, but arguably still better than you because Swords Dance and Chlorophyll give him sweeping potential. Now that you have Flare Blitz though, you can claim to be at least as good as Glaceon, who has a similar offensive power level but a very weak defensive type and generally poor abilities. The problem with being you, Flareon, is you’ve got one hell of a Flare Blitz, but you’re lacklustre in both speed and defence, which makes you really easy to kill, and all of Fire’s weaknesses are to really common attack types (Water, Ground and Rock – including Stealth Rock). In comparison with other physically-oriented single-type Fire Pokémon, well… Darmanitan is somehow faster, tougher and stronger, and has a better selection of physical attacks plus the ridiculousness that is Sheer Force; while Arcanine is faster, surprisingly tough, has Intimidate, is flexible enough for a physical/special mix, and can heal with Morning Sun. Hell, even Rapidash is faster and has arguably a better physical movepool than you, but at least she has the decency to have bad abilities, average defences and a weaker attack stat. You could go hang out with Rapidash, I guess?
