Badges - Buy Gems or Save for conversion?

[Harrypott]

Justice points are not being wiped come cataclysm, you are allowed to keep the cap to invest into your first tier of items for the first raid content.

I'm guessing Shodokan has hit the cap, and coverting it to gold is somewhat pointless for him compared to getting 1 bit of gear since he has HEAPS of gold. Where 99% of other people it would be better to convert badges to gold if they don't have as much of it as they would like.

Either way if I had heaps of gold and heaps of badges I would probably be keeping them till closer, whats a bit more gold when you already have more than you can use anyway compared to an item you can only get from justice points?

Not to mention that 1 or more bits of gear will help one to be that much closer to being able to box the new Heroics etc etc.
