I think you all who are complaining about the prices of ectoplasm are stressing too much on the trader prices. Imagine this: instead of buying the materials, find it! What a concept... (oh and if you don't want to read all this, skip to the last paragraph)
If I'm with a good party, the times I've been through FoW or UW, everyone in the party gets at least 1 shard/ecto... so what's that... 125g for an ecto/shard? So hey, it'll take a while to find 105 shard and 105 ecto...
But really, do you want (a) spend time monotonously farming until you have enough money to pay for the ridiculously priced crafting material? or (b) have fun collecting the items and working your way through FoW and UW... (who knows, maybe there's a hidden crafter or collector in the zones... you'd never know if you farm for money)
And then it all boils back down to the: "You don't have to get this armor." If you do want it, then you have to work for it... but oh no! "I have to spend *time* to get it!"
And look, if Fissure armor were easy to get... then there's nothing that makes it unique anymore... it becomes commonplace and undesired.
Imho, it's just like life... there may be that extremely nice luxury car you want to get, but it's above your budget... so what do you do if you really want the car? Save for it. Will it take a long time, for most people: yes. What does that long length of time serve to do? It makes the feeling that once you finally are able to get the car oh-so-much better. Accomplishment. I know I will feel extremely pleased once I have enough to get that fissure armor (money and materials set.... 100shard/100ecto to go

). It's a feeling that you accomplished something great -- and worked hard for it.
Sorry for the long rant... Bottom line: Fissure armor is possible without having to buy from the material traders, so stop looking at those prices!
