For those readers who may not know what expertise is or how it works, it is a stat which appears only on PvP gear and increases damage, damage reduction, and healing in PvP only. Due to the recent changes in Patch 1.2, it is basically the best possible stat you can have in PvP.
I understand that it can be frustrating to have gear only work in specific scenarios, but I believe that a "PvP stat"-type system is the best solution for preserving balance. I also understand that many people object to it from a design standpoint, saying that it is clunky or that it wouldn't be necessary if class balance was truly perfected. I disagree.
It needn't necessarily take the same form as the one we have (you could make it more complicated, have PvP gear lack essential PvE stats, or have multiple PvP stats that do different things), but overall I believe that expertise offers the developers the best tools to balance PvP while continuing to offer exciting and engaging content in both PvP and in PvE without fear of ruining the prevailing order in both systems.
The problem of motivation
|Vader does NOT need to find new ways to motivate them.|
Now, not everyone who wanted to do Operations also wanted to do PvP, so these people were left with a choice: do something you're not really interested or invested in for the easy gear, or spend a lot more time doing what you want, but which may or may not be effective and has no guaranteed reward for time invested.
If both sets of gear work equally well in both scenarios, we'll see pretty quickly that most people will feel pressured to take the quick and easy path which, with the current evolution of PvE content, will almost definitely be PvP, since winning is not a requirement and losing continuously, while slow, would likely still be faster than trying to PuG with an 8-person Explosive Conflict group. And again, even if it were faster to PuG EC, there is no guarantee that you get what you need.
Ultimately, the best choice should be to let players to what they love, and reward them by giving them better tools to continue doing it - not to do something else.

A controlled environment
Another thing that a PvP stat offers is the ability to make across the board adjustments to all classes in the areas of damage, damage reduction, and healing.
As of 1.2, these things all scale differently with expertise (eg. You get a larger damage bonus from expertise than you do a damage reduction or healing bonus), but Bioware has shown that they are not afraid to re-balance ratings to better accommodate the play experience of their subscribers. They currently have the ability to look at any of those three things via their metrics, decide that one of them needs to be adjusted, and then adjust it across the board. Now that's flexibility.
Ultimately, I wouldn't be surprised to eventually see an "expertise co-efficient" on abilities to change their effectiveness in PvP. We've already kind of seen this with all healing abilities (Trauma, for example), but I'm talking for specific abilities. Maybe particular abilities will be encouraged in PvP, and so they gain some bonus damage or healing in PvP. Maybe some abilities will have their potency toned down for PvP, but some of this penalty will be offset by expertise.

I believe that players should be doing what they want and getting rewarded appropriately for doing it. Clearing PvE content should not entitle you to top tier PvP gear, nor should achieving an amazing warzone rating allow you to breeze through PvE content. That they are separate isn't a bad thing! It's just more game to explore and experience.
