SE must be drunk.

Actually, no, there was a huge difference.

I had a leveling static where I played PLD, and we had a THF and a SAM. At lvl 33, the more famous skillchain was Tachi: Enpi - Viper Bite, used with Sneak Attack and Trick Attack.
The thing is, SA+TA-VB was so powerful that keeping aggro on that was very difficult. So, frequently, the SAM provoked the mob away from the tank, so that the THF could align behind the tank and behind the mob.

But, if you knew how to hold aggro really well, you could keep the mob on you, while the THF stayed behind the mob and the SAM, and the mob wouldn't turn around.
In FFXI, DPS were much more powerful but were limited by how many enmity the tank could generate. When you ended with a good tank as a DPS, you really felt like you didn't have to hold back and it was a great feeling, for the tank and for the DPS.

And this shows me how much you don't know anything about 11, even while trying to compare it to a totally different game. Good job also on killing your DPS on 11, if you ever go back, should try utsusemi rotating as a ninja or actually having the Sam tank through seigan and third eye as well as taking no damage keeps your hate up and both dish out more damage. Also you should have your THF split SA and TA, since SA works off Dex and TA works off AGI, would need two different sets for those, stacking them, more so at a low level always results in a DPS lost. Also make sure your thf is using a cross bow at such a low level due to the low base damage of daggers, making them useless on just about anything other than their DEX, R.ACC, and R.ATK. Other wise the only thing their good for is TH if you're trying to collect on items to get your crafting up.

TLDR:
Please learn to play FF11 before trying to compare it to a totally different game.
