I've played BLM and RDM to 75 on an Elvaan, and I've played BLM to 75 and RDM to 67 on a Taru and I believe Taru has some distinct advantages.
To make up for the MP my Elvaan lacks over my Taru, I have to idle in and use lots of +MP/HP to MP gears, as well as spend a good amount of effort on macro systems that swap out gear dependent on how much MP I have. +MP stuff is useless if swapping to your nuke set causes you to dump 2~300 MP. Likewise it's harder for an Elvaan to reach the 75% HP mark to make Sorc Ring kick in on BLM.
Not to mention ugly pendant. My elvaan blm needed less than 335 mp to activate ugly. A taru could activate it 130 mp earlier with the same gear. That allows them to not only activate it sooner, but it's also significantly easier to keep it active all the time when you can have as much as 630 mp (allowing for 3-4 nukes), and still have it active, instead of needing to be lower than 400 (only allowing 2 nukes).
To make up for having less HP, Taru can idle in -%PDT gear, which is much more attractive than being an Elf wearing Intensifying Cape and a Hedgehog Bomb...
Of course every race should be using pdt gear still. Of course anyone who thinks tarus die easily either plays with a bunch of retards who don't use any (ie 90% of people, because it's just too hard to macro in an earth staff after casting), or are idiots themselves. Tarus don't really die any more than other races when played properly.
Also my Elf has to carry like 1/3rd more gear since I need a Max MP set as well as all the basic Nuking/Enfeebling gears.
While taru doesn't benefit from full mp gear as much as other races, since it doesn't help much after vert, it's still useful to have any time you're resting to full. Starting a fight with 1200~1400 mp is kind of ******* awesome.
Yeah but the "sh*t is situational" still applies as well.
As long as you're not planning on handling every single dilemma by Sleep/Nuking for the rest of your life, Taru doesn't seem like the best to me. Then again I believe Hume is the best FFXI race in general, cause I'm a sucker for balance.
Honestly, it's not that situational. Unless you absolutely never do anything that requires you to nuke/bind/etc where the extra int helps, or anything where your mp would be stressed, taru is
the best race for rdm. Is it the best race? Honestly, the differences between the races for melee jobs is very small, and since the differences between them for mage jobs is relatively much larger for all mage jobs, i'd argue that yes, it is. Of course That doens't mean everyone should just be taru. If you want to play a wide variety of jobs, than hume is a pretty good race, especially if you like melee jobs better than mage jobs. However, arguing that taru is not the best job for rdm is beyond ridiculous. Again, it may not be that much better, depending on how you play, and what you do, but it's always better, if only by a slight margin.
