Ok, they're useful if you want to be inferior.
Of course, another, less demeaning, and less elitist way of saying it, would be to say: "they are useful if you don't want to spend the time on Ursines." Of course, if you're an elitist, it sounds ridiculous to give anything value if it's not the best for it's purpose... but different people value their time differently.
I don't have the Ursine trials completed. In comparison to someone who has Ursines, am I an inferior choice for procing blue? Yes. But do I still proc blue and get the job done? Yes.
Now, we could get in to semantics as well. How many times do you, and will you proc blue purposefully over the course of your entire FF life. A few hundred times? I honestly have a hard time even making a guess. But let me just get to the point. If it takes you 60 seconds longer to proc blue because you have an inferior TP building weapon, how many hours will that be over the course of your FF life? A few hundred times 60 seconds. Now, how many hours did/will you spend on the superior weapon for just that purpose?
You obviously don't have to come up with specific numbers. The purpose of that last paragraph is to give you an idea of cost-benefit. If you are spending time to conserve time later, is it actually worth it? For some yes, for others no. Right?
That's dumb. Until you have level 90 you are inferior. Ursine is nothing else than a waste of time, you could build a large part of vere while you do the retarded trials.
You're wrong too. A waste of time is a matter of perspective in this situation. Most people would agree that the purpose of playing FFXI is to have fun. If someone is having fun doing "retarded trials," no matter how ridiculous that sounds, it's not a waste of time to them.
or you could just have both
Right. If you already have Vere, or you've done what you can do on your own, or you just want something else to do to better your character, the Ursine Claws can be useful for at least the one purpose of TP building. Along that same logic, dual wielding a k-club and an octave club would be faster for the purposes of TP building. So actually, what you should be doing is using those 2 clubs to find blue hint, then staying with them if it's club, swapping to Ursine if it's h2h, and swapping to [insert fastest TP building staff here] if it's staff.
So also to follow that same logic, if you don't have all those weapons, or you aren't working for those weapons, you are also choosing to be inferior.
