Um, I disagree with that concept. You find a bunch of water types, and yet a good majority of them are pretty useful. Jellicent, Gastrodon, and Keldeo are good ones, to name a few. There's also Floatzel (who functions well in lower tiers). Seismitoad is somewhere in that area, too! I'm agreeing with Jake in that Fire-types are actually far and few between in terms of strength.
Think about it: This generation has brought us both Chandelure and Volcarona. You've made your point with Volcarona, who can be a formidable Pokemon in the hands of the right person. And of course, Chandelure is the same but...at the same time, people want variety, y'know? They don't want their choices to be limited, and let me tell you why: if you're going to use Chandelure, you're probably best off scarfing it for maximum potential. If you're using Volcarona, you'd probably best do a Chestorest set for outstalling or just go plain out offensive, but the problem with Volc is that you'd best have a spinner, because Stealth Rock is its worst enemy.
It's nice to have so much variety to choose from, and that's why water types are such a diverse and yet excellent type to choose from. It's like, you don't go without seeing a team that has at least one water type (competitvely, that is). Gyarados, Milotic (I would assume she's seen more on lower tiers), Quagsire (both low and high tiers), and the list really goes on and on. You have choices to choose from, and that's kind of what I'm hoping with this generation's fire types. Of course, an abundance of them probably would be asking too much, but it should be enough that people should be able to have good selection out of them.
I mean, good selection. Not things like Heatmor. I doubt people still remember that thing exists. .__.
