Yeah i think so.
MNK is the only class without any real range attack and it might be no part of MNK´s identity, but it´s definately a unique design choice compared to the others. MNK has SSS, chakra or FS instead of any range options and i think it fits the class very well together with all the positional requirements. I really don´t want to see range attacks or copy & paste job gauges or whatever on MNK. I want every class to be unique instead of having nearly the same tools or even job defined tools. Nothing would change my mind here. I get the wish about it, but even away from my "unique" opinion, i won´t say it´s needed in any way. We got other tools to work with.
Yes they seem to be not useless, but in the end, they´re. Bloodbath for example is a broken skill when you´ve to deal with addpacks, but where do you really need it, when you normally have a tank? Same with the shields... Yes they can be lifesaver and i´m one of the guys, who use all given tools. But in the normal way, healers have to heal everyone and such solo defs doesn´t have that big impact. On the other hand you´ve such situations where 3 players (1 heal, 2 dd´s) might be down and it seems great on paper to survive the next aoe meanwhile the 2nd healer can rezz. But even here it´s going to be a wipe a bit later or at an enrage in 99% of all cases. Mantra is the worst raidbuff too. Healers have their rotations and those 10% seem to be a lot, but it normally ends in overheal too.
Overall, the content is just not made for those tools or they´re just way too bad on singletarget etc... Not even tanks are forced to use tons of defs in any content (maybe ultimate). This should change and overall all classes should get some more unique defs to work with, which definately are a real help for the healers or give us the possibility to tank more than 1 boss hit in a savage raid. I don´t even want to talk about the lack of mechanics around Esuna, interrupts or CC. I would just repeat myself again.
We haven´t much tools left after some years and SE still doesn´t even make use of the last of them. It´s really sad.
(Imo they were only useful for me on MNK, when i played several bodzja fates out of a group. I timed their use, survived somehow and even got multiple solo invites in the end.)
