The people saying you're a horrible player are in the minority, most of us who have cleared coils know that fights like t5/t9 require at least a half decent PARTY. It doesn't fall down to one player.
That being said, I know so many people who cleared t5/t9 solely through PF just by creating learning parties, then practice parties, then clear parties. It took a while but they did it. So the reason I get so annoyed with people asking for nerfs, is because if you actually want to clear the content it can be done, you just have to put the effort into it. If you are not willing to put that effort in, or don't think it is worth your time then that is completely understandable, it just means you want to play the game a different way and I accept that, but I do not accept that you want content to be made easier for people (on top of echo + better gear).
Echo is fine, if people want they can still click echo off, so I have ZERO complaints about that at all.
Then there is the whole 'elitist' concept.
I despise that term. Do I think I am better than others because I have a static? God no. I have simply put more time and effort into end game raiding than you.
As for the whole 'I don't have time for a static' it's not a great argument, a static doesn't have to be ridiculously hardcore. Mine has mandatory raid days of Thursday night and Sunday afternoon. These are the days that worked best everyone, between that we organise if we can go other nights of the week, some weeks we go twice, some weeks we might go most nights.
If people don't like the idea of a static that's fine. My FC doesn't and they raid casually through the week with whatever party setups they can get together and so far they have cleared t10 as an FC.
As I have said, if you want to clear end game raids, put your time into end game raids. If you don't then that is absolutely fine, but don't start asking for nerfs then when others get annoyed by that start calling them toxic and elitist. We don't think we are better than you, we've just put more effort into the content that we find the most fun to play.
With that being said as well, now that lockout is lifted this whole us and them mentality has pretty much gone, I'll farm t10/t11/t12 to gear up my offspecs in PF, I don't expect a clear everytime either, and I'm also happy to help people out with t5/t9 groups if i see them struggling in PF. The most toxic attitudes I see lately are from the people who want the first clears. I'll join a PF group and pretty much throw music on and chill out and relax as I do the fight, then I see the people in party chat raging out, and it's usually the ones who wanted the clear. So this whole toxic attitude goes both ways.
