Yup, someone from SOE has finally stated officially that the professions for FSCS opening is RANDOM. The way I worded my question should have left no doubts.
"All the steps (not just holcron) are random, as has been stated in the past.".
I will, of course, continue along what I percieve to be my pattern (my theory fits in with the response GarVa gave, a randomly assigned pattern starting at a randomly assigned first profession. In my case, I believe my 3rd holocron will be either Architect, then Smuggler will open, or will be silent, and Architect will open. Either way, I'm pretty confident architect is my next profession). However, in light of this statement, I'll probably end up giving up on even that theory.
Anyhow, I've said many times I'll look at both sides and other ideas, regardless of what I believe, and I'd never hide information to further my own thoughts. Here's the official "debunking" (or attempt?) of pattern theories.
