You know your gear is optimized horribly when..

[Ryans]

It really bothers me when people say this.
Crit is a very important stat because there are classes that just outright suck without it, and determination is 0.325 of a main stat which adds up a LOT.

People say they are useless because it doesn't truly matter what 130 gear you get as long as you aren't way over the acc cap. All the gear has the exact same stat values per piece of gear and the only difference is the ~.01 dps per point between the stats. You can stack whatever stat you want and still perform fairly similarly to any other of the same job at the same ilvl and player skill.
