When the Call to Arms weekends first started for Battlegrounds, there were a lot of complaints about the honor junkies causing losses and generally noobing it up. The regulars were right to a point, playing Battlegrounds on non-honor bonus weekends usually means you are playing with people who know what they are doing. But, in my opinion, because both sides had honor farmers during the Call to Arms weekends, it pretty much evened out.
Since Patch 2.3, we have the Battleground Daily Quests. They are great for cash, honor (if it works) and even experience if you aren't max level. They are also easy to get, since you just have to be the qualifying level of the BG in order to do the quest. You don't have to do pre-quests or collect anything -- nothing except win a BG to complete the quest.
So now, on weekdays and when other BGs have honor bonuses, questers are infiltrating the games that used to be reserved for the well-practiced BG regulars. The difference between the Daily Quests and the honor bonus weekends is that it is different by realm. During the Call to Arms weekends, everyone has the same Battleground for bonus honor. If your Daily Quest is for Warsong Gulch on your realm, the other realms in your Battlegroup have different BGs for their quests. The noobs may all be on one side, with the other filled with veteran twinks.
