I'm not sure how I should judge this as I'm not familiar with how the game works. Why is this a bad thing?
It hurts immersion. This isn't an FPS where you can just switch between campaign and multiplayer; it's an RPG, and you're playing as the same character in both PvE and PvP. They shouldn't be treating it as a completely different setting that requires no transition whatsoever.
The PvP itself is quite confusing, and strangely enough, I have yet to see any, well, PvP in it. Just some incredibly overpowered NPCs and monsters. Also, I'm not sure how much of this is due to the quirks of the PvP area itself and how much of it is due to the fact that my alliance happens to be sucking a big one in this campaign and we only control a couple of bases, but there are only a couple of wayshrines available for teleporting to, which basically means I have to travel across Cyrodiil on foot, and whenever I die, I respawn on the very edge of the map where my bases are. It's every bit as tedious and frustrating as it sounds. The only thing of note I managed to do was find Cheydinhal and complete a few quests there.
