5-10% is a lot. It's by far enough to let one race outshine another one.
Actually,
everything except for the 3 STR you quoted is enough to force people to play a race they don't like just to be good in a certain class..which is, btw, not even making any sense at all, because we are supposed to rank up ALL classes.
Oh, and yes, I DID read all the posts in this thread.
So a person HAS to be stupid and unable to listen to the voices in all the things just because he is born with a big, strong body? Wow, way to go for ingame racism..
And basically, the people were right most of the time, because with such a huge difference as implied, it's impossible to be better then a Taru.
Maybe better than a Taru who used crappy gear and never tried to play his class with any effort, but you have to compare people with the same mindset, and that would be someone caring for the Conjurer job:
A Galka could never be as good as a Tarutaru CNJ, simply because he was "born" a Galka.
No "thinking out of the ordinary" will change that.
And to say something about your opinion about a free-to-choose-game like FFXIV needing such differences even MORE:
No, it doesn't.
Because even if you give any Rogaedyn crappy magic and every Miqo'te lots of Dex, it still won't distinguish peope from one another, simply for the fact that at least 1/4 of the players in the entire GAME have this race, and because of that, the same base stats.
In reality, it's even up to about 40% of the players with Miqo'te for example.
The only thing which will really make people individual is their OWN stat build.
It's the only thing every individual can decide on his- or herself.
And we are getting that back with future patches, so..
Still, NO for race differences.
