I am down to the last semi-useless course, learning to jump farther with my ships than the currently accessible galaxy actually allows me. Hey, at least I can call that an investment into the far future.
After that all that is left are the three Combat Stims courses. Stims, as I mentioned once or twice already, are utterly useless to me. In almost every conceivable combat situation I am running out of focus about ten times faster than any of my physical stats. Which means stim-related courses are just a waste of resources.
