I only got to 30 back in the day thanks to IB. Not everything has to revolve around the raid. It doesn't break anything to have 1-2 pieces during each IB event. It's great for johnny casual (like me).
Perhaps its just the MMO player in me whos used to PvP gear being a lower item level than PvE gear, but thats really how it should be.
PvP gear should be balanced around PvP with PvP perks to enhance the players capability versus players, while PvE gear should be aimed towards PvE and perk that benefit versus AI.
Both can be used in both situations, but to be effective end game PvE you should actually be required to do PvE activities, not fully gear up doing PvP.
Same goes for PvP.
Wanna be part of the top 1% in PvP? Better play some damn PvP and get that gear aimed towards that cause raid gear aint got shit on PvP geared players.
