An observation...

For rogues: 20 agi = 1% dodge

For druids: ~14.7 agi = 1% dodge

For everyone: 18.9 dodge rating = 1% dodge

Since 1 dodge rating costs the same in itemization points as 1 agility, gear with dodge rating is not good. Both rogues and druids should want gear with agility in place of the dodge rating. (The lone exception is that bears might want pieces which have a substantial amount of both agility and dodge rating, as this would let them obtain a very high amount of dodge from a single item.)

Alas, rogue tier 4 and 5 shoulders...

I agree.
