the hytbold armour is fantastic for new 85s, and most classes get amazing bonuses that even make them better than the Greater Erebor armour in many cases...
example: +10% healing on Hytbold Watcher for minstrel (4-piece bonus).
That bonus alone gives you far more than you could get with +2-3% stat increase on greater erebor set.
My Hunter is lucky enough to wear 2 Horse-Lord pieces, but wears 2 pieces from Hytbold bowmaster, and 2 from Hytbold Huntsman.
Why? the two piece set bonuses. -10% bow inductions (i.e. +10% dps) and +5% crit chance.
I'd take -2% stats any day to get those kind of benefits.
