Tried your idea out this evening, as I have 400+ converters from random drops on my toon. Soloed two AV portal mission at +4 x 8 to pick up 13 random recipes. Out of the 13, I need to convert 11 as they were selling for less than 300k on the AH. I used 78 converters to convert those 11 into enhancements that were selling somewhere between 4 to 10 million. Probably took around 30 minutes, to make the enhancements, check AH for current pricing and which enhancement out of the set sold for the highest price. The first 3 I convert I got exactly what I was looking for on the first try. 4 through 9, it took at least 3 to 4 tries and one of them I rerolled 6 times. The other three I did the random "out of set" rolls and it took several tries to get descent set and a few more tries to get the highest priced enhancement. Roughly, if everything sales by morning based on current pricing I should make around 70 million give or take.
Conclusion:
Based on time spent, the cost of converters (if I had to purchase them) and how long it generally take me to clear a random AV portal or radio mission solo. It wasn't worth the effort I had to put into it. Given that I can solo a ton of content at max level, I could of ran three to four PI radio missions or cleared a five mission farm set in AE with time to take a poop and make a sandwich and a guarantee of almost 100 mill in influence, in roughly the same amount of time. Not to include drops.
Helpful hint:
If your looking to grow your bank account, it's more or less getting on a small team that is crushing out content, one mission after another at +4 x8. Or figuring out at what mission level your toon can solo at and hammer out content as quickly as possible.
KEEP IT SIMPLE.
If you know the recipe and the enhancements are worthless then dump recipe on the AH for 1 influence and move on. Don't waste your time trying to making it, then listing it on the AH for what you think somebody willing to pay for it.
Generally I make the good recipes prior to logging out. if its a set I can use in a Alt toon I drop off at the SG base tables, if not I list it for one influence, take what I get and move on. If I get a purple drop, I make it and I put in the base table, I don't sale it. -This is where those converters come in handy. Changing those to complete set with out spending influence-
Salvage:
I have 8 racks in the SG base, two for orange, 2 for yellow and 4 for white that are generally pretty full. I sale all my yellow and white salvage as my toon gets full. I don't waste time on the AH, I list everything for 1 influence and move on. Even when I have ton of one particular rare salvage in my base supply, I still list the rare for 1 influence and I press on. I take whatever it instant sale is and jump into my next mission.
The bulk of the influence your getting get in game, is from running content. Everything that drops you feel that you can part ways with is just bonus influence. The more you can quickly collect the more you can quickly sale. I logged out this evening with 2.6 billion in influences and that after supply 5 others toons and giving my other two SG members roughly around 750 million to help out their first two 50s to get them start.
