Actually I realized something I had forgotten. I said crusader was better for dps because that was true when those things were current. Agi did not originally give 2 ap per and the crit from it did not originally work on poisons (which didn't really do much damage anyway). I'm kind of unsure now, I mean 100ap on a proc versus 30 ap all the time with a reasonable amount of crit at lower levels. Depends on the uptime on crusader.
The strength part is 100% false. I don't believe the crit part is true either, but I can't confirm. The real way they stopped plate from rolling on leather was that if you are wearing even 1 piece of non plate gear you lose 5% strength. Kinda took the lazy way out. I don't recall rogues actually wanting strength gear ever (unless you count way way back when they put strength on rogue leather). Now maybe the DS strength proc trinket for pvp or something.
