Just to add, this isn't a moan about how the set isn't good for my talent build, or a complaint about how its only good in PvP.
Currently, Arcanist just is plain pointless, straight up. No other class in the game is wearing green items over epics to boost their damage, and thats just wrong on every level.
And introducing good items in BWL & Zol'Gurrub doesn;t cut it either - unles you expect Mages not to ever raid MC. You can't a fix a problem by ignoring it and hoping people will go elsewhere.
