Can We Please Get Some Transparency With Stats?

...Get your relevant numbers as big as possible?

For the most part: Yes. But which stat gives you the biggest benefit is a bit more difficult to determine. Accuracy is probably the worst offender here - it's the most important sub-stat up to a point, then completely useless - and it's ONLY relevant in raiding/EX content. And there are 3 different caps for it - and they differ for each boss. Transparency where?!.
It should be noted that simply knowing your crit or spell speed percentages isn't going to tell you how much the stat contributes to your DPS. So the suggestion of this thread wouldn't actually help that. It would show how pitiful parry scales, but that's about it.

In the case of Accuracy, it does not have an actual cap. It has a point of maximum impact - which you note there are three different points and they differ for each boss - but that is encounter-specific, and front/flank/rear specific. Unfortunately, tooltips are written once, and then forgotten about, basically. They are not dynamic. They do not change based upon the content you are in, nor the value of the stat you are hovering over.

So long as tooltips are static, not dynamic, the desired "transparency" will not occur.
