Yes, it is extremely easy for a character with Indomitable to surgically take out a single opponent.  I agree the resulting player fiat can be kind of annoying; I find it deflates tension and makes scenes flatter.  But if you follow the fiction and make things real, you'll move the game away from easy kills into more dangerous territory.  The Indomitable's reputation will precede her.  Smart leaders will use cannon fodder and feints.  Smart lieutenants will goad their leaders into attacking the Indomitable so that she can do their dirty work of regicide for them.  People will become frightened, and refuse to deal with her, and suddenly resources will dry up.  You can't eat fear. 

My favorite thing to do to an Indomitable is take aim at the things and people they love, when she's not right there to save them.  Where's you called shots now, Clarity?  Huh?  HUH?  (Sorry, flashback to my last game.)

And there's always setting the players at each other's throats.  Indomitability does not work against PCs.

I let characters narrate some outcomes, especially if the outcome is very definite: the PC very much got the local doc into the sack, very much killed the local doc, etc.  Rather than narrating yet another NPC death (or seduction), I hand it over to the player to say how it happened.  It gives them a chance to detail what their character is about.  It's meaningful if Wembley dodges and weaves and dances about before landing the perfect blow, vs. leaping on the doc with a scream and beating his skull into paste.  It's meaningful if Wembley engages in a playful romp and some pillow talk, instead of just dropping trou and squeezing his eyes shut until the doc is done.

It's a little more work, but it might be fun to use what you have as a framework for character-specific custom love letters.  Switch up the pick list and maybe even the stat.  You can also have them point to E.g., an Angel might have roll+Sharp, and pick from:

* You've heard this hold does a good business in medical supplies.  If you go looking to restock, you get twice what you pay for.
* Unfortunately, the reason there's so much supply around is that nobody knows how to use it right, and everybody's *really* excited the hold has a new Angel.

Brainers are good at convincing people to just hand stuff over.

Brainers are good at convincing people to forget something and leave it behind.

In the settings I've played, just about anybody can shoot somebody else, but not many people can dig into your brain.  So muscle is cheap and plentiful, but pet psychics are not.

This is really neat.  I may start using it tonight for my ongoing game.

One question: the countdown clocks normally start at 0 and get worsse as they head towards 12.  Why did you chose to flip it?

I tried to sign up for your game. Man, those slots went quick!

I do!  Though, really, everyone should just play Skinners.  They're the best.  One of them can even be in a mask.  Oh, dear, now I'm imagining a bordello specializing in roleplay.  "Here comes Rolfball, someone tell Jujube to break out the Brainer outfit."
