OK here's a big tip for you 5-boxers, on how to make a lot of extra gold (500g+ on my server, YMMV) it takes at tops 20 mins and fits right in with your daily quest loop. The only downside is if you do it too much then you'll flood the market. I do dailies 1-2 times per week right now and I have no problem, but I am sure if you did this every single day then you'd kill it.
Go to Blade's Edge Mountains, in Ogri'la and The Crystal Spine areas there are 4 eggs that spawn. If you put 35 crystals into each egg then it summons up a 5-man dragon to fight. Each dragon (Rivendark, Furywing, Insidion, Obsidia are the names) drops a scale for each person in the group, along with a good chance of dropping a depleted item or some valuable green jewelcrafting cuts. If you take all 4 scales and combine, you get a Deathwing Brood Cloak, a L70 BoE with random stats. So if you 5-box it then you get 5 cloaks for 135 shards. These cloaks sell for 100g+ for me -- even the crappiest stat ones, as they can also be turned into an Apexis Crystal to buy the Ogri'la blues/epics. Be sure to advertise them as such on trade chat as a lot of people don't know about that.

In the last 32 dragon kills I've gotten 6 depleted blues (~150g each) and 1 depleted epic (gave to guildmatealong with 4 green JC recipes (100-150g each) and of course 40 cloaks (min 100g). Including all the greens and greys this is easily at least 5-6000G, or 180g+ per dragon kill. It takes 35 shards a summon so you get 5g per apexis shard.
"But where do I get all the shards to summon" you might ask? Do the 4 Ogri'la dailies and you get 60 per day per character. 35 are spent doing the group apexis emanations quest, leaving you with 265 shards, you'll easily pick up another 15 off kills giving you enough for 8 summons per day.
"But, my AH is terrible / I flooded the market and I can't sell the cloaks" then you can just DE some or all of them right into large prismatic shards, easymode! Don't forget the dragons drop a lot of depleted items and JC recipes that will sell nicely even if the cloaks do not. I'd estimate probably 250g even if you're sharding all the cloaks.
