Hello! I didn't seem that kind of thread, maybe I am wrong to make one but I will anyways
Little background about myself. I mained BLM for a long time until 3.x where I switched to Dragoon. Then I went Samurai 70 at SB to quickly revert to Dragoon. My favorite job? SAM > BLM = DRG. Unfortunately, there's really just one I can play seriously.
Job balancement is something that everyone has a different opinion on... Some people feel Samurai is fine because they have those 40k Direct Hit Crit and it's fine to think that. However, I have a different opinion and I feel certain things need to change. "Meta" is a curse which top tier groups find the most suitable group to clear content and most casual follow the "Meta" which top tier groups use. I'll avoid mentioning tanks and healers since this is a main DPS thread.
To me, 4 DPS comp should always be, 1 Melee, 1 Ranged, 1 Caster, 1 Wild Card. The Wild Card could be anything. However the "Meta" disagrees with that for various reasons which are valid. The "Meta" is like this. NIN - DRG - (BRD/MCH/SMN) (pick 2 of the 3) You could rep DRG for MNK or a ranged for RDM. It still would work.
The very first problem is raid utility synergy. A buff multiplies a buff. What I mean is that on my Dragoon. I have Heavy Trust (+10% buff) and Piercing Debuff (+5% buff) which means I have 15% passive damage buff. It is wrong. The way it is calculated is like this: 1 * 1.1 * 1.05 = 1,155. Take note that DoT tick aren't affected by weapon type debuffs. Now... Trick Attack doesn't add my Dragoon 10%. It gives 11.55% Because I always have a multiplier of 1.155 and if I stack my Dragon Sight, it now gives 12.705%. Raiders line up cooldowns because of that. Unfortunately for Samurai and Black Mage, they do not possess a raid utility meaning they do not help the raid unlike the "Meta" group. Someone can argue that Samurai bring Slashing Debuff, unfortunately for the "Meta" Ninja is a staple.
Ninja is a very big issue. Not Trick Attack but Shadewalker. At 4.0, SE stripped the utility toolkit from BLM and WHM to benefits all casters and healers. However, Shadewalker is mandatory in raid. It is so potent and strong, that a group who plays with a ninja and suddenly rep a ninja with another melee wipes on farm content. Shadewalker completely changes tank rotation and gives them a 1000 DPS. It is that silly. It is very simple in my eyes about Shadewalker. It should have become a role action! If the goal of SE is to make all fights tanked outbound of a tanking stance then they should bloody give the action to all melees. They also could just remove it which would force tank to adjust but would make Ninja less mandatory.
Weapon type debuff should also dispensary. I deeply apology but Piercing Debuff, at 5%, is still too strong on Ranged DPS. The only caster that trumps a ranged DPS is Summoner because they got absurdly buffed to the point they are viable. Now think of it. Why would you bring a selfish DPS class like BLM or SAM when you have a SMN which simply outdps then and provides a 2% raid DPS buff. Even if they buff them to match SMN DPS. DPS + 2% raid buff > DPS.
I am aware it is very likely we'll see true job balancement in a future expansion but the meta hasn't changed in the slightest since 2 expansions. Monk is a bit more viable but DRG utility still trumps Brotherhood.
Finally, this is purely my opinion but balancing with buffs only is bad in my book. Yes, nerf does make it feel to most people that it's an undeserved punishment for a casual stand point. Unfortunately the community follow the hardcor prog. 3k viewers stream happened during UCoB. Despite not playing as dedicated as them, most people aspire to be like them. What originally motivated me to be doing hardcore prog back in 2.x and 3.x was admiration from that community. When that community rules out a job is mandatory such as Ninja. Then it is too strong and must be balanced down or clip some of their personal utility toolkit.
But yeah... I like playing Dragoon. I wouldn't mind being able to play Samurai but it's just not viable. Especially in content like UCoB. I'm better off being useful to my group lol.
