Still nobody wants to know this, I'm from FFXI and it hasn't got anything like Wow/FFXIV raiding and I climbed from the bottom.
No video footage, or link to your parses, though asking for fflogs not sure how GMs would respond here so risk at your own leisure. Without knowing what you're doing in the fight we can't give insight what you're doing and if the raid leader is speaking the truth, and I mean if.
