Well, this is where a little knowledge is a dangerous thing.
If you don't know how the Thargoid war works - because you've not been paying much attention, since it hasn't hit any important systems before - you can grab a ship, show up to Sol, probably get blown up repeatedly but nevertheless see all the Thargoid stuff for the first time and be excited about it. At some point, maybe in a few weeks, you'll get a message that the Titan is vulnerable and you can rescue (what's left of) the Sol system ... and essentially get to speed run thro.......
Oh I know how the AX war goes, I wrote that in the post you reacted to. Been participating in the last four Titans go boom.
Still, knowing all that, this is the defense of Sol. It should have been organized differently. Hence, I'm taking my Crait II to Mars High as a base and fight Thargoids around Earth
PS
And we will win whatever we do, all this end-battle is scripted.
