First a little context. My guild is 1/9M atm and we got cutting edge Guldan. I joined them towards the end of the last raid cycle as they were progressing on Mythic Eli. I only raided heroics prior and had no mythic experience but they were still willing to give me a chance. I managed to pass the trial easily and they quickly geared me up. Even though there were countless wipes on Guldan, it was amazing when we finally killed him.
We have been progressing nicely on H TOS and killed Kiljaeden in the first week. I was even awarded some tier pieces and am now 1 piece away from 4 set bonus. However, I have been noticing that I have been performing comparatively worse in logs compared to many others in the raid. I have a 2 orange parses, a few purples, and the rest are blues and greens, putting me at 70% average percentile for heroic and I was at 51% for M goroth in last night's kill. There are about 5 or 6 people in the guild who consistently hit orange and purple and average around 85%.
So I'm somewhat in a conundrum now. On one hand, I feel like I'm somewhat being carried while others that might perform better are being sat and I don't want to hinder progression. On the other hand, the fact that I have been given loot makes me think that they want me to be part of the team and I don't want to abandon them. I am considering either taking a break from raiding altogether or join a "less skilled" progression guild. I have tried reading detailed guides on my class, watching videos, analyzing logs but I can't seem to push it to the next level. This has led to increased stress levels and raiding is becoming less fun as it only becomes a matter of numbers as I try to catch up to others. I kinda miss the old days where I raided heroic with my old guild and can goof around. In mythic, I feel like I can't make a single mistake and have to play optimally all the time just to keep up with others and it feels like a job. I don't really want to leave though because these are just a great bunch of guys who don't have an elitist bone in their body despite all this. Any thoughts or advice?
