NIN FCoB DPS plea for assistance

[Kuinu]

Good evening. I am rather tired as of right now, so the post might not be the tidiest one, so pray forgive me for that.

I've been doing FCoB for about 3-4 weeks since I came back with a group that miraculously happened to need a melee dps, spoke spanish, and was nice enough to let me in their static. However, after doing some research...

...It seems the range of the average NIN on any of the instances of FCoB is around 450-500, and that talking about around IL115. Well, I am a IL123 NIN, and at the training dummy of my FC house I deal around 515 DPS sustained for 4 minutes, while on FCoB, specially today on T10... It hardly goes ever beyond 420.

Now, I don't want to write a long essay about how I looked up everything and tried to deal with it, so I'll make a list of stuff I've done so far:

[Kuinu]

-Getting re-used to my rotation? Check.
-Sharpening my opener? Check.
-Use AutoAttack? Check. I put Standard Camera mode on for that very reason.
-Leveled LNC and PGL? Check.
-Keep B4B and IR on cooldown? Check.
-Use Invigorate when at 560 TP? Check.
-Use Shukuchi? Check.
-Apply/Maintain my DoTs/Debuffs? Check.
-Use off GCD abilities? Check.
-Try not to drop mudras when doing Huton > Suiton > Raiton? Check. Though yes, I do fail sometimes, but usually I try to make the best of it.
-Use trick attack with B4B/IR? Most of the time. I also make sure that Dancing Edge is on to launch the buttsecks, and do Spinning Edge to give me time to use up a buff to do Trick Attack.
-Kassatsu? Check.
-Accuracy? Check.
-Food? Check.

-DEX Potion and poison potion? Not yet. I want to improve the DPS I can deal on my own first before going on to those.
-Learn mechanics of every boss? Check, I'm right now trying to learn T12 though.
-Have a good connection/VPN? Nope. I have only a 20mb internet contract, of which only a half and a bit more actually comes to me, and I believe that I shouldn't have to pay up a VPN to be a good NIN.
-Have a good computer? Yes, the game runs smoothly even with good quality graphics.
-Train everyday? At the dummy, yes, whenever my student time allows me to.

It needs to be said that, whenever I have to do a Mudra, if it's a Fuuma Shuriken, it barely makes it to the CGD timer to continue my rotation. If it's Raiton/Katon, my attacks must stop for a brief moment. If it's Suiton/Huton/Doton, then my attack stops for several seconds, around 3 seconds, not enough to reset my rotation. I don't know if the Eu servers still are located in Canada or whatever, but last time I tried to ping to the IP direction, it gave me 71ms, so I don't think the lag is to blame.

[Kuinu]

It is also worth mencioning that I get nervous easily, given my "special mental situation", let's call it. Usually when I get nervous, while I try to focus on one task, I'm unable to remember the process of the other task. So then I admit; If at the moment I'm focusing on evading every mechanic launched at me, I might forget to reapply my Huton or DoTs, keep using Dancing Edge, use Huton earlier (These two as some kind of self assurance). But then again, in T10 and T11 is not the usual, though I still get nervous.

[Kuinu]

I've already researched around Google and Reddit about possible performances that could be done, asked several people in and out of the game about the issue, did a lot of tries and tests, even began to get special aid related to my mental issue and nervousism. Yet, I still can't reach the acceptable DPS. If this keeps up, I'm going to be raidless again, and struggle to get through everything again, like with SCoB... And boy do I want to prevent that from happening ever again.

If you excuse me, I'll go try to get some sleep, since I wasn't able to, trying to find useful information... If there's anything that can piss me off enough to ignore sleeping, is being unable to play videogames when it's the best I can do, and I cannot figure why.

Thank you very much for your assistance. And my apologies for the several posts. I had to get beyond the 1k character limit somehow.

Could you upload a video of you doing your rotation?

Off the top of my head, I can suggest you to use some VPN.
You are right, you should not have to pay for it, but it actually helps a lot.
More over, if you're European, you are playing on a server that's in Canada, so yeah. You'd be paying for them being cheap, but it's even more worth it. Not to mention the plenty of times the infrastructure (not SE's, just the internet infrastructure) has issues, which happens quite often. A VPN often helps you avoid such issues.

Also, practicing the fight over and over is immensely helpful, and your DPS will improve as time goes on.

Plus, having a Warrior off-tank placing the combo so that you don't have to is quite helpful aswell.

I'll try to upload a video today.

Sadly, all of that is beyond my control. People won't wait for me to practice fights over and over until I'm completely melded with them, neither internet seems to be a huge factor on DPS, given by what I've researched so far.

[Kadas]

Internet is not usually a factor for other jobs, but as a Ninja it makes much of a difference, as you're supposed to squeeze in mudras inbetween GCDs, so the faster you are without making mistakes, the more DPS you will deal by the end of the fight.
