Which trinket should one be using as a mage for pvp, in addition to the pvp trinket? I was going to get the flow of knowledge from wintergrasp, but apparently it has a 45 second cooldown with a ~10% proc, plus some resilience. I really couldn't be arsed to farm the honor for the battlemaster one anymore as I've farmed honor far too much already, so I'm just thinking is the flow of knowledge any good or is it just useless for arena? Don't wanna waste my marks...

Or would some pure DPS (pve) trinket be best to for super nuke? Something with base spellpower / crit with a use: add spellpower/haste rating for 20 seconds on a 2 min CD?

Or maybe the gnomish lightning generator, even after the nerf, for a little extra nuke?
