Well, i'm using bots to make my SBD fructify as i'm still a very very small minnow / fish and i see it as an investment to get my games project more known, if i knew a better way i would do it of course but i don't... Maybe when i'm at a level like yours i may be able to stop using them and just delegate some sp.
I'll be sure to follow you and see how it goes for you following this path as an experiment ^^
(Also i don't even know if i'm using the right bots or how efficient it really is, i may even loose sbd doing so... )
