I get tone doesn't translate great online sometimes, so off the bat just want to say--not going for angry, hostile, harsh, any of that when I disagree in this post. Mild and conversational from my end.
I'm not bothered at all by the fanservice, lack of realism, lack of practicality, etc. for Viera and their starting gear. Not even bothered that the Veena (who apparently live in snowy landscapes) are gonna be freezing their bunny butts off if we stop and think seriously about it. And I'd like to suggest, gently, that this is a kind of silly thing to get worked up about.
Reasons are this. Final Fantasy as a franchise has been both notable and consistent about suspension of disbelief in the name of fun. Fun might mean "badass" or it might mean "hot" or "funny" or any number of things. It's pretty equal opportunity in terms of gender. You can get waifish characters wielding swords twice their height. You can show male and female characters running around freezing areas in swimsuits. You can have the Warrior of Light fight Zenos in a fat chocobo mask.
Viera are genderlocked right now yeah, but I'm sure it's only a matter of time before that changes. Same with Hrothgar. When gender is unlocked for Viera, if the guys are similarly fanservice-y then that is supremely fair imo.
But beyond that. First, we can always put a Viera character into something more modest. Second, there are a ton of games out now with character customization as an option where either female characters are modest or outright barred from feminine clothing. There are more practical, realistic game options too.
The approach to Viera is very in-keeping with the tone Final Fantasy has maintained overall. Suspension of disbelief is consistent in how it's used and how it isn't. If you want something practical, realistic, devoid of fanservice, etc. honestly you might be happier with a different game.
