Noticed today that using the item Wintergrasp Commendation (Wintergrasp Commendation - Item - World of Warcraft) inside the Icecrown zone counts as 1 kill towards the PvP daily [Make Them Pay!] (Make Them Pay! - Quest - World of Warcraft)
So if you have extra stone keeper shards or wintergrasp marks of honor you can trade those in for the Wintergrasp Commendation (BoA item that grants 2000 honor) then fly over to icecrown and use them to easily knock out a daily.
