Right, my equipped trinkets are http://www.wowhead.com/item=62050/darkmoon-card-tsunami and http://www.wowhead.com/item=58184/core-of-ripeness and I just looted http://www.wowhead.com/item=71336/petrified-pickled-egg. I can't see the Egg edging out the Tsunami in any way, but can it be a replacement for Core of Ripeness? I'm still a week and a half or so away from the Valor Points trinket.
I don't really have any mana issues in Firelands, except for maybe on Alysrazor (have yet to try Majordomo and Ragnaros as a healer) if some DPS guys messes up and the Restoration Druid is too busy healing the second tank, but maybe that have something to do with the use-effect on Core of Ripeness. I expect even less mana trouble when the nerf hits (obviously).
Probably silly to make a thread about this, but I'm dead tired and ill, so my mind isn't at 100% at the moment.
Thanks!
