People gear their jobs and play them in many different ways, this is true. Unfortunately, just because someone does something one way, for whatever reason, does not necessarily make it better or even viable. I could TP in all STR+ gear on my Monk, but I know I would be doing less damage that way, and thus be worse for it.
FFXI math has been figured out for a very long time. It is not difficult at all to look at two different sets and determine which one will do more damage, create more hate, cure more, or enfeeble more accurately or more potently.
Since I've been keeping up with other threads, a specific example which works out fine is your THF. You say you gear for Dex, Agi, and Chr with 0 Haste, and I am given the impression that you do not change gear between TP and Weaponskills, let alone Job Abilities. In general, I can tell you right now hitting faster would do more damage. Changing gear for weaponskills and job abilities (and thus not wearing CHR while TP'ing) would increase your damage. If you want the differences to be quantified, that is shown in numerical format, you can post exactly what it is you do use and I can compare it to an alternate set.
I'm not saying this to "Bash" you, and I do not feel that I am being rude or insulting at all. I am simply offering you the opportunity to improve.
