The main reason you are seeing more bots in PvP right now, at least at the high levels is that most regular players have all the gear they need from hp and jp so they have no need to PvP. After the 25th and after the bot is up and running smoothly again you'll notice few bots per bg simply because there are more real players to fill the spaces in bgs. If you are worried about the bot in bgs run it as a healer. Have you ever been pissed off at a solid healer in bgs? No, no one has the people who can tell you're a bot won't care cause you're filling an under utilized roll for the most part, and all the other botters shouldn't care who the bots are.
