I don't know how you do a majority build that ends up being a totality build, but whatever big guy, keep going on and on and on. One day when you get a chance to play with a PLD who focused on STR and you realize he has not only a better sustainability than you, but also a higher enmity threshold, you will get wise.
I did all VIT and then re-spec'd to 2 STR to 1 VIT, and my sustainability did not drop at all, but I now am able to keep enmity through even the most overzealous of healers. I may even re-spec to a full STR build as the numbers are explored further. VIT can be boosted through gear, as it is the primary stat on just about all PLD gear.
I don't care what you do. I have been a PLD since day 1 on FFXI until now. Before the shield buffs on PLD I was one of the first to use a Terra Staff to tank with primarily, to all the nay-sayers like you, who a couple months later were buying up Terra's Staff. Then all the nay-sayers like you who said PLD/RDM was a horrid idea for JoL, but soon it became the accepted method to tank.
You do what you want, but I will continue to advise other Paladins on how to get the most from the job. At the end of the day, I keep my party alive and win. If my party is upset about that, well then, I will go ahead and get a measly 400 extra HP and loose enmity on the regular.
And before you bother replying, keep in mind that I have no intention of reading it or responding to it. I am spending my day leveling by running DF and getting groups through Stone Vigil. I'd much rather prefer practice than theory.
