I don't want every single special attack to have a corresponding physical attack or vice versa. I prefer Pokemon to be asymmetrically balanced. For example, giving a physical fire poke a second typing for more STAB attacks.
What I would like to see are special fire pokes having more utility than just being pure sweepers. Typhlosion was good at what it does, but it got boring just spamming flamethrower and the occasional Blast Burn/Eruption.
Oh, before screwing me with "Flareon can't kick", explain to me how Jolteon can Double Kick then.
Double Kick has quadruped Pokemon turn around and kick out with both legs like a horse, hence Ponyta being able to use it. Looking at a list of Pokemon with access to Double Kick will show a lot of quadrupeds. Blaze Kick, on the other hand, is more of a martial arts type of kick with one foot. Thus it makes sense that Flareon wouldn't be able to learn it.
That doesn't explain how the Deerling line can learn Jump Kick.
