It may be an unpopular choice, but I've been capping almost every week since Patch 3.3 doing PvP.

1. It's nowhere near as bad/toxic as word of mouth has misled people to believe.
2. As you're facing real players, there's no stale, scripted events.
3. Your job, for the most part, plays differently in there, so again less of the same ol'.
4. There's also a roulette for Frontlines, and 8v8 Feast does award tomes. Less than a roulette, but also takes less time.
5. You also earn Wolf Marks which you can buy (non-essential) PvP gear for glamour, desynthesis, the cute cheerleader minion, and (currently) 2 orchestrion rolls.

Again, might be an unpopular choice for all the wrong reasons, but give it a try.
