I had +enmity but never found it terribly useful. If we're talking about important events, for a long time now tanks like Nin/Drk, Pld/Nin, and Rdm/Nin (not to exclude some others) have had no problem quickly capping their cumulative enmity. Trick Attack w/ or w/out WS seems to hardly be needed, and only a miniscule contribution at best. Further, at a lot of endgame events, you have multiple tanks that want to keep as thin a hate line as possible, and oftentimes trick attack can only mess up that hate line.
If you're talking dynamis and einherjar, it's unimportant, as those are huge burn-style activities where tanks aren't important, and it's better to just share hate among the DD's as they attract it naturally.
For solo, you don't need it obviously. For duo, I think it can be pretty good at times. It kind of depends what you're fighting though. Sometimes when I duo with a Rdm/Nin (or even a Rdm/Whm) it's often better to let the hate bounce back and forth. And if I lose hate when I won't want to, it's usually easy to get it back with a SA, SA+WS, or collaborator. This may not be the case for everyone though. Duo aside, I think misc low-man situations is where trick attack plays a bigger role. I used to do 6-man merit-party style limbus and I did a great job of splitting hate as evenly as possible among all of our DD's. The problem with stacking enmity though is that it is in some sense arbitrary and futile, as sometimes you just want to give someone a little itty bitty amount of hate, and other times you want to give a person a whole lot of hate. So sometimes extra enmity will have helped, and other times it would not have helped at all.
All and all I've had +enmity for years and found it pretty lackluster. I don't think I've ever once thought (if only I had more enmity on my trick attack). The only time I've ever really wanted enmity is when I've been tanking, but I can count just as many times when I wish I'd had less enmity. Sorry this doesn't actually answer your question directly.
