Best off researching prices on other games currency then look at what sort of money per hour you can make botting/grinding for it in that game, take into account cost of the game subs and upgrades then factor in how easily you can shift the game currency.
To be honest dude most people on this forum are idiots who don't know how to setup honorbuddy let alone work out more complicated bots or set their own macros up so you won't get much helpful advice.
I can tell you to go bot My Little Pony but YOU need to do the research as without that you can't know if its profitable, and really this is something you should be doing rather than making the OP and waiting for people to tell you.
Bear in mind too that most people making money off other games won't exactly tell you what is great for making money as that cuts into their own profits, its like people giving away a private GB2 route that gives 250+ nodes per hour
Don't take my advice the wrong way I'm just trying to give you good solid advice that you shouldn't take personally, good luck with your future botting.
