Its no surprise that you dont understand the Hessian plot since you know little about the organization itself.
The Red Hessians are one of the largest organizations in Sirius. The Hessians are fighting on two fronts (three if you count the Wilde), one being the Corsairs and the second being the Rheinland government. And, they have been doing quite well on both fronts.
Now, in your post filled with sarcasm, its clear to me that you know little of Hessian lore, so I dont know what qualifies you to trash talk it. The Hessians are (failed) miners after all. Most of the income they get is through Blood Diamond trade and "donations" that are collected from miners/traders throughout the Omega systems and Rheinland space. Adding to that, the Hessians also have several mining operations going on, not to mention their own production of capital ships. The resources for this, as mentioned before, come from multiple sides.
The Hessians also have a strong ally in the SCRA (so far). Taking over large installations in Dresden is quite doable with the help of their supporters and allies of course, since the Rheinland Military presence in that systems is somewhat depleted. The crippling of the Rheinland Military in the Omega systems is not rare either, since the asteroid fields and gas clouds provide a significant advantage to the Hessians in that conflict. Though, the Omega systems are still a bigger battleground between the Hessians and the Rheinland Military since the unlawful presence is more firm within Dresden (even with the Altenburg present in that system).
In your complete FL time (which is not big I might add), you obviously failed, or perhaps even refused to understand anything about the Hessians, which is fairly obvious.
@OP:
I must say that I dont know how to feel about the situation with the Corsairs in Omega 47 (regarding the Hessians). Letting Casablanca be recaptured by the Corsairs could be quite a blow, but establishing another base in the system at the same time could maybe prove to be even more rewarding (depending on where its gonna be located).
I guess Dresden would be still set as a priority, even with the loss of Casablanca, which I still see as a major change/loss. Though, again, I am a bit surprised by this move. It reflects the feeling that the Hessian-Corsair war in Omega 47 is going into the Corsair favor, which wasnt really the case so far.
