Won't be long before part 2 is here. When it is, high probability there will be new high end armors and fissure armor won't be as desirable. So I don't think ectos are the greatest long term investment. So what is???
1. Rubies and Saphires - Reasonable, they said they were inclined to make them valuable, but how valuable, more or less than current prices? No one can say. A good place to put some wealth, but anyone who puts most of their excess wealth here is taking a big risk. There is, however, some upside to compensate for the risk.
2. Monster Fangs, Claws & Eyes - Again, even if they give them a use in Part II, no one can say whether they will be more or less valuable. If they are given a use, their drop rates may be adjusted too. Again, perhaps there is some upside to compensate for the risk.
3. HOD Swords - VERY risky...who knows what new items will be introduced in part II that will render the HOD sword obsolete? Keep one if you use it...
4. Green items - terrible, prices still falling, supply is ever expanding. Perhaps some gains when the new players flood in, if you buy the good stuff dirt cheap shortly before part II -- if you can time that right.
5. Sup Absorb and Vigor - Probably somewhat safer than the above methods.
6. +15>50 items with vanity skins. This seems like a very good choice, although obviously still some risks.
7. Perfect 2 attribute gold wands, truncheons etc...A bit more risky than 6 because who knows what stats the next Brohn's wand type item will have.
So far my wealth is still in ectos, with minimal diversification into rubies and saphires. I am not super rich, I could barely afford one true +15% >50 vanity skin item (and still have 1m plat) but I'm still getting uncomfortable as ecto prices keep falling.
