Dear PLDs

[winsock]

You are the only common denominator in every one of your dungeon runs. If your dungeons are bad, maybe its not the healers fault. This goes for all the QQ threads and posts on this forum. If you regularly struggle with 'bad players' so often, maybe its not the people around you that are the problem. Anyone that I know who id consider a 'skilled player' never whines about dungeons. But the forum sure has a lot of 'bad rng' groups. Coincidence?

I think your argument is weak.
While an unskilled player could be delusional in thinking they are skilled and that everyone else is the problem. An unskilled player could just as easily be delusional in thinking they are skilled and that most players are skilled because of how the other players perform comparatively. For example, a tank with terrible DPS may not think there are that many bad DPS players in the game because the bad DPS players are doing much more dps than the bad tank. An unskilled tank may pull so little almost all healers seem good or at least sufficient.

'Bad' is also subjective. The wall-to-wall dog section pull of Ala Mhigo presents a good example. One of the problems that can occur when attempting this pull is that the healer can be targeted by multiple AoEs, which forces them to move and stop hard-casting.
If this causes a wipe, who, if anyone, is bad?
The PLD could have covered the movement with clemency or possibly HG.
The WHM could have covered the movement with an insta-cast.
The RDM or BRD could have offered support
