I'm sure many of you have done the math and thought about this, but I wanted to start a discussion about the new injectors/extractors for being able to keep multiple accounts paying for themselves. My thoughts begin with the idea of never actually training this toon any further, so assume a cyno alt, trade alt, miner alt, etc. Let's talk a little math:

So you can generate roughly 2mil SP per month with a perfect remap and at least +4 implants in your 2 stats you are training in (I'm taking that fact second hand, as I've never crunched the numbers myself). I like battleship training to 5 so far to steal from as you can squeeze 3 injectors out of that 4->5 progression without ever changing the skill training.

That equals out to 4 injectors per month. Assuming you can generate the 4 injectors per month and buy the extractors off the market, you would be required to have an isk profit of 1/4 plex per injector to cut even on paying for a plex just through injectors. Currently plex is around 1.2bil, so 300mil profit per extractor/injector pair is required. This is easily achieved at the moment as Amarr is showing about a 350mil spread between extractor buy orders and injector sell orders. In the future? Who knows. I expect extractor prices to climb later, but not quickly. The question is will injectors go up when extractors do or will the price of SP end up being lower in the long run. A glut of SP was removed when this first happened and now it will be dependent on the SP farmers to keep up the supply. Assuming the demand keeps up

Lots of future questions, so we'll stick to a "for now" scenario. Right now you can sustain multiple accounts through injectors, profit off of them if you add in PI on all 3 toons on the account, and profit more if you actually use the account for isk making endeavors. I know everyone is upset at CCP coming down on overlays and that they seem to be on an anti-multibox bent right now, but in terms of multi-account stability we have just entered the Golden Age for EVE as now you could theoretically run as many accounts as you want as long as you are willing to never have them increase their SP count. You can hand-make a "perfect" toon to do one particular thing and then do it forever (or as long as the margins hold out between PLEX/extractors/injectors) without paying irl.

I was pretty shocked to glance in here and see nothing really written up about this. I can only assume to everyone else this is "obvious" but either way I wanted to kick off a conversation and see what everyone's thoughts were. Also, anyone who has old trained accounts well above the 5mil SP mark can melt those puppies down for massive money. I went from being "space middle class" to "I can buy a titan but meh" nearly overnight. Having a big bankroll may entice some older players back to go whelp ships for funsies or to start that huge mining fleet they always wanted.
