Full PvP honor gear in WoW costs roughly 600k honor, NOT including weapon, offhand or ranged weapon. (Including low end arena weapon, add 35k honor)
Arena weapons (2 types, ones which cost 3.6k arena points and require 2350 personal arena rating, and the lower end ones which cost 35k honor and 1.2k arena points + 1850 personal arena rating)
After roughly 10 hours of AV yesterday (probably more), counting in queue time etc, I got 20k honor.
So to obtain full honor pvp gear + arena weapons (lower end) you would have to spend:
Full Honor gear = 635k honor required = 31.5 days x 10 hours a day/20k honor a day
Low end arena weapons = 3450 arena points required = Average of 900 arena points a week (1900-2000 rating 3v3/5v5) = 28 days
And finally, after spending all this time grinding away for arena/honor points just to get better gear, you get to experience the same game again, except now it takes a couple seconds longer for you to die.
inb4 pve. Haha, no.
