Crafted accessories are an issue.

Kidala: you forgot your 4th point that goes along wit the first suggestions:

4) Tune content so its not nescessary for tanks to wear pentamelded in the first place due to insane DPS checks.

This one is needed if one of your first three suggestions become reality and honestly, an encounter shouldn't be weighted only on DPS and Enrage checks. Many people complain about the current state of the PLD for example, but the real problem is not the class, but the current raid content not being properly tuned.

I totally agree with this, tanks should be tanks and healers should be healers(I didn't have room to mention this with my first two posts.) We shouldn't be relying on everyone in a raid group to put out as much DPS as is possible to meet these enrage timers. The DPS jobs, sure, because, well, that's their JOB. The current meta requires everyone to squeeze out as much DPS as possible, including the healers(but they're not giving healers accuracy, now? Make up your mind on this, SE.) While this is going a bit off topic, DPS checks need not be the only checks that these fights have. Tank checks and healing checks are also a thing.
