Different Gear Sets Still Pertain?

The different gear was introduced to solve the problem of players gearing up for pve via pvp and vice versa. But is that a problem? In the olden days, epics were easier to get via pvp, but that is clearly no longer the case; quite the reverse, Where to sell World of Warcraft accounts  actually. So do the original reasons for the different gear sets still pertain?

Honestly, this is a personal choice of the developers and never made much sense to me.

What does it matter if you use one for the other. Normalizing on one type of gear would make game play easier for the vast majority of players.

You could move between PvE and PvP seamlessly and enjoy more aspects of the game without either picking one or spending 40 hours a week grinding both to "be competitive."

I know the reason, I played in Vanilla. The point is, the distinction makes it problematic for everyone. Developers have to fight through these issues design wise, and players have to fight through them game wise.

Both parties would benefit from simply removing the distinct gear requirement for both.

One type of gear for both situations.

The problem is tied to RNG vs. Static methods of acquisition.  PVE still relies on RNG (more so at higher levels of play), PVP still relies entirely on currency.  Having PVE & PVP gear be the same thing means many people would PVP to fill slots for PVE.  This is precisely what happened before Burning Crusade, and quite a few players were furious about the situation.  

If you thought people were mad about being "required" to do dailies, where to buy WoW accounts wait until you see the response to being "required" to PVP.
