Having said that, armor penetration is still by far the best PVE stat for PVP, miles and miles ahead of haste/expertise, and a big reason why PVE geared rogues still have a big advantage against pure PVP equivalents. Why can not Blizzard release a separate set of rogue arena gear with armor penetration ratings instead of crits? Casters sure complain a lot about melee itemization, but they get to choose between crit, haste and spell damage on every honor piece! Why can not we at the very least get to choose between armor penetrations, crit and hit on ours? The biggest question is of course land of chaos Gold; will Blizzard keep the tournament realm running after Blizzcon? Without the tournament realm it would be much much more difficult to arrange this.
