I have already commented on my initial statement coming off as harsher than I intended, but the truth remains the same. No one should be utilizing outside sources to comment on another person's performance. If these tools were integrated into the game. Have at it. Also, my most recent posts have elaborated on my stance and in my opinion have been reasonable discussing how this game presents content to the player and what they are expected.
At the end of the day, be clear about what you want. Be upfront in your parties and let people be. And actually, I DO play this game alone 90 percent of the time except for roulettes and clearing a normal raid or dungeon for the first time. And in that content, unless you are wiping consistently, NO ONE should be commenting on someone's DPS performance. Save it for your Savage and Ultimate parties YOU created, with CLEAR RULES and UPFRONT PERIMETERS.
