Made a new arc - but can it be soloed?

Heya all - I finally got around to creating my latest arc, and while I did my best to make sure it was playable and interesting and all that, I'm concerned about it being soloable (since not everyone wants to run teams).

Now, for the record, I tested the arc on my grav/kin controller (the one w/o SB, ID, and IR), my dark/psi defender, and my en/en blaster. Each of them managed it okay - challenging, but not too hard. Does that mean I made it too easy? And if I make it harder, will that bias the arc against other ATs?

The arc in question is the 5-parter fast-paced "Cause and Effect" (454140) by @Samuraiko. It's heavily geared toward storyline rather than XP, but could I trouble a few folks of varying ATs to give it a runthrough? Feedback on the arc itself is really secondary to how challenging it is on a particular AT.

Thanks in advance for any help,

I posted a review in my thread; I gave it three stars.

I was able to solo the arc with a 40 KM/SR Scrapper. A second try with a 35 TA/A Defender failed in the last mission with the EB at a sliver of health. I had some bad luck in that fight and probably would have won if the breaks were even. The Defender also drew five random Boss spawns in act IV; fortunately the ally took care of all but the first.

The extra Bosses were not your doing. It was the wacky spawn system. For some time now at party size 2 it's been possible to get a spawn consisting of a single Boss and a single Minion, both possibly at +1 to your relative level. Sometimes you'll get an entire map spawned that way. There's nothing an architect can do about it.

Oh, okay, I appreciate you letting me know!

I'll try to check this out this weekend, what's the level range? You'll see it first on twitter.

40-54. As I mentioned, I'm less interested in a review of the story than I am in the mechanics of timed missions and bosses, etc. The story, as Venture pointed out, needs work.
