Not sure what you want me to get from that.

So, just telling your sub what to do will ALWAYS make them do exactly what you tell them the tick you tell them, right? Hell, the first thing you need is to decide whether to say yes to this being your sub or not. If you simply say yes to every single person that tells you "Hey Ill do you a sub" or "Hey I'll be your sub" then you are indeed a noob unless all of those guys (which is 99% impossible) can do you a sub with more effectiveness than their cost.
Btw, what SAGE and GML you reffering to?

I don't use subs nor would I, the only valid reason to have a sub ever is if you are just stalling an annoying person and trying to get your units back to kill them. Well, the only Sage and GML with a massive sub empire.
