I saw a post on someones view of paladin in its current state and the thread wasn't very well received, I think it's because the author got caught in the typical trap of arguing "viability" of the class. So I'm gonna make a quick disclaimer and say this post is in no way criticizing the viability of tanks, you can literally make a class viable with 2 buttons it's not that hard. This is actually regarding what makes the tank classes unique in respective to their names.
First of all the design team seems to have made defense a very passive stat, and most of a tanks survival comes from skill mitigation (and of course the healer) so in turn that has kind of made the paladin shield nothing more than just being aesthetic. Sure paladin can block, and sure you can do it every so often but it's very unreliable and... I'm not sure, but I think the occasional block was meant to make up for the lack of healing (or barrier) in their basic rotation because all other tanks have that but paladin doesn't. So the only way to get a reliable use out of your block is to use Shelltron, however all other tanks get a different variation of that exact same ability so how does that make paladin unique? *shrugs*
I wasn't around during the beginning of Stormblood, but I was told that among the warrior players they weren't exactly happy with the whole inner release+fel cleave situation, it took a unique class and basically turned it into a meme. But the designers liked it so much that they gave variations of that same 5 button spam rotation to paladin and dark knight? Paladin also has a mini spam in its rotation with Atonement which personally I don't really see the point... I think that gunbreaker is the only one that's unique in that case so good on them.
Anyway I can go on forever, but the point is that none of these jobs are really that unique in anything beyond aesthetics. It's strange to me that they are so desperate to get every class perfectly balanced that they didn't realize that they just managed to make all the jobs exactly the same... or maybe they did realize that and that's their ultimate plan, who knows.
I have tons of ideas to make these jobs unique, but I won't go into that. For now I'll just say that I don't see a problem with minor imbalance. I don't mind seeing paladin as the staple, easy mode tank class that it started off being, because when you think "Tank" in any game it's usually paladin or Sword+Shield. It would be cool to see paladin being the tank class with the highest defense and best damage mitigator.
I don't mind seeing Warrior become the highest damage, highest self healing and highest HP tank in the game the way it originally was. Warrior was difficult, but when people played it right it was admirable and fun to see.
I don't mind seeing Dark Knight as the inner darkness job with the highest angst level and unique love for anime. There's alot they can do with this job to make it less copy pasta than the rest.
Finally believe it or not I actually kinda like Gunbreaker, simply because I think it's the most unique tank due to its rotation. I think it can be WAY better, but it does make me a bit hopeful that they intend on advancing back to unique-ness and job identity.
I know they're worried about the meta, but the nature of "the meta" will always choose one job over another. These hardcore players don't much care for identity or lore, the biggest thing for them is viability and efficiency, so if Paladin has a single second of faster efficiency in a boss fight than Warrior due to animation lag or whatever, then the meta will chose Paladin. I think SE should focus more on making each class "unique" and reasonably ABLE to do end game content, rather than making sure that every class is represented equally in the end game logs.
EDIT: Hmm after thinking about it, I think what I want is a new unique experience every time I switch to a new job. Kinda like I'm actually playing a new game. I feel like at one point they were actually on that path, but that has definitely changed over time. Is it too much to ask? What do you think?
