PvP all day, everyday: Concerted Efforts (A) or For Great Honor (H)
It's back! Perhaps of all the new daily quests that have arrived with the goodness-filled Patch 2.4, arguably the most confusing and mysterious one is the repeatable quest called For Great Honor for the Horde and Concerted Efforts for the Alliance. It is a dinosaur quest from the days of the old Honor system but made its stealthy return last Tuesday with a few tweaks. It was so stealthy that it didn't even make it into the official patch notes. It is also not searchable in wowhead through filters (e.g. added in Patch 2.4, PvP, etc.) or by name (e.g. "For Great Honor"). The references to the quest in thottbot or allakhazam both refer to the old repeatable quest albeit the quest description themselves have been updated to include the new requirement -- an additional Mark of Honor from Eye of the Storm.
Unlike the old quest, the new and improved For Great Honor -- which probably has the same ID tag (confusing poor old wowhead) as the original quest -- does not give any reputation for old world Battlegrounds. Players grinding Battlegrounds rep for the Conqueror or Justicar titles are flat of luck and must do it the hard way aside from being crazy for trying (yeah, okay, I'm one of those people). The very first time players complete the quest, it awards 11g 99s and 314 Honor points at Level 70. Subsequent turn-ins will only award the 314 Honor.
Because of the removal of diminishing returns to Honorable Kills, Honor points are available for use immediately, making this quest the most efficient way to earn additional Honor. Because it is repeatable and not a daily quest, players with stacks of 100 Marks of Honor from all Battlegrounds can accrue 31,400 Honor points right away. Of course, it is possible to earn more Honor from more turn-ins. Winning in all four Battlegrounds, for example, can give an additional 942 Honor from Mark of Honor turn-ins. For the many players who have full unusable stacks of these items, it's an excellent way to free up space and gain Honor points at the same time. Needless to say... make sure to save some Marks for those welfare epics! On a final note, try to complete this quest in the less populated cities such as the Exodar or Thunder Bluff, specially if you're turning in a whopping 100 times. Less populated cities will have less lag and less chances of players zoning in from Arenas or Battlegrounds to get in the clickable way of your turn-ins.
