For Necro's out there looking for a tradeskill, treating your research as such can be profitable in the end. I know many of use "farm" to make plat. I have done a little but I found that I simply didn't have time to farm and level. I chose to work my research skill. In the end it paid off I spent a ton to get to 191 but I also saved a fortune making my own spells and now spells to sell. At 191 skill level I completed my level 60 spells this weekend!
If I estimated I would say I have put about 15k into my skill and gotten about 11k back from sold spells. I have saved myself around 20k in making my own spells. Everything from here on out is pure profit. So the 4k investment was well worth all the hassles.
For the record I did not have 15k to invest! I bought and saved words as I had the plat. Made my spells first and what excess I had, I sold then bought more words etc.
A word to the wise.....starting out make spells you succeed in all the time and gain skill. Ex. if you can successfully make a level 35 spell and it doesn't tell you that you no longer benefit from it. Then just make those spells till you have used up all the experience. This will save you a ton of money, give you some spells to sell and quickly raise your level. I got gutsy as I progressed and jumped way ahead and lost some plat in failures due to my lack of patience!
I also researched for others free to gain skill level. I tried to partner with a trader that specialized in words to get them for a reduced price and at times free in return for the spells that were successful. I made my own trader only for spells and undercut my competition even at a loss early on to have plat flow.
