Some infos on the upcoming Burning Crusade:
Replacing Gear
* Item mudflation is so far on the extreme side of things. You'll be replacing tier .5 within an hour or two of playing.
* Blue rewards are on par or better to what you would normally get out of instances in WoW classic relative to equivalent greens
* Trash greens are roughly MC. BWL starts off with low level quest drops. AQ is hard quests/high level drops, and Naxx gear gets slightly ecliplsed with the difficult 5 man instance gear- but Naxx gear is most certainly on most come 67, short of stam bonuses.
* (How much T3 will I be wearing at lvl 70?) Honestly, 1-3 max based purely on stats. Possibly a bit more based on set bonuses. New gear is just obscene, especially stat based. In addition, most new leather/rogue gear specificly is AP + Agl.
* blue level 65 quest reward weapons are in the 60-62 dps range for 1h
* expect to only start replacing naxx items from 68-70.
* i've replaced 7 items, most of which are my oldest epics (gurubashi dwarf destroyer, quick strike ring, claw of the black drake, and so on)
* The 2 first instances are rather easy, and the loot it drops there is comparable to BWL loot more or less.
* But a healing neck that dropped from the last boss of hellfire rampart was 85% of the cthun neck.
* As for shadow gear you will start changing that from the get go.I replaced my Sash of whispering secrets with a green quest reward
