My rogue didn't get an upgrade for either of his daggers until the week before 5.4 dropped, and that included daily heroic scenarios hoping for a 516 piece... As others have said, RNG is RNG.
Remind me to go on my gearing runs with you, though! ;D
In terms of LFR, didn't blizz say that alts would have an increased chance of gear
to help speed the gearing process up? Might be just for the first 3 raids(msv/hof/toes)
but I could've sworn they said that in a blue post some time ago.(sorry i have no recollection
as to when, nor can I provide a link, just going on memory)
