Few things... First off Elvvans are indeed stroger than Gilkas. They are equal to start and get stronger. Secondly,
"Elvaan shouldn't have as much str, but more agil and dex."
This is incorrect. To take the warrior job as an example, Elvvans start with9 str, 7 dex, and 6 agi. Gilkas Start with9 str, 7 dex, and 7 agi.
At level 70 Elvvans have 74 str, 54 Dex and 50 agi. Gilkas have 70 str, 58 dex, and 54 agi.
The real difference is in vit and HP, at level 70 Elvanns have 1268 hp and 58 vit where Gilkas have 1409 hp and 66 vit. However, if you want to tank in higher levels as an Elvvan (or any race) you will probably be a paly and, without going over all the stats again for a pal/war (they work out to be similar ratios) the equalizer for Elvvans is MP. Elvans have nearly twice as much MP (221 vs 113). This is actually an advantage. Not necessarily to make up for the total HP, but rather, to hold aggro. As you know cureative spells pretty much draw the most aggro of any type of spell comporable for the level. The ability for Elvvan palys to cast twice as many curative spells means that they are much more effective at keeping aggro and, without the ability to stack taunts like you can in other MMO's, this is quite important to a tank. The additon of having the highest Mind (effectiveness of each heal cast) or any race makes Elvvan Pal/wars the ideal tank in FFXI.
"Im kind of glad this elven like race is different in that they are taller, and stronger than the elves we all know of. "
Actually, this game finally got it right =). Most MMOs borrow alot of the race mythology from Tolkien-esque writings (yess I know alot of his mythos was constructed on Norose folk lore but I'm not going there now =). In Tolkien's work the Elves were, infact, much sturdier and more phisically imposing creatures than any other race. In the Silmarillion (where I was a King of Elves ;) the toughest of Elves were able to kill lesser gods that had gone bad (Balrogs) single handedly. So, Square really relied on the "traditional" ideal of an elf in creating the Elvvan race, rather than that travisty, pip-squeek, High elf of EQ and the the elf of EQOA. GJ Square :D
