A few thoughts on my experience with this arc:
Firstly, I second a lot of other sentiments in these comments, such as: Doc Buzzsaw's dialogue is the best (and feels very true to her character, though maybe those are redundant); there are probably too many ambushes; overall good arc, good story, interesting mission maps, a bit on the difficult side. Other things:
Crey is interested in moving to Kallisti Wharf? Ooooh, foreshadowing?!
I definitely don't want this to be a strike force, for purely selfish reasons - if it's made a SF I'll be unable to solo it with all the AVs and so will probably never do it when it goes live. I'd much rather it be a fakey-fake TF/SF like the Ouroboros arcs, most things in First/Night Ward, etc.
How exactly did we get to the Abandoned Sewers? Didn't seem to say (or I missed it), though I guess through Boomtown is the most obvious route. Also... will we get to have Freakloks roving around the Abandoned Sewers if that's where things are going down? (I almost want it to become a co-op zone though I'm not sure whether that would work out story-wise...)
Speaking of which, I was disappointed we didn't get to see a lot of the Freaklok given how much they've been teased... I know more is coming, but can we have a Freaklok boss or something to come along with us on the final mission, so as to get more of a taste? I assume in the future something will go horribly wrong and/or right and we'll be up to our Detail 1s in hostile Freakloks, but I'm impatient I guess!
