…when someone is making a suboptimal move in the tournament? We hear Christopher’s reaction, “No, don’t move away, use Hypsersonic Assault for a third time!” However, we can’t see or hear your reaction.

For myself, though, what makes watching people playing Tactics (and many other games) interesting is seeing what decisions they make differently than what I would do in their shoes. Different players have different play styles.
Unless you're talking about things that are strictly suboptimal, like dying with +1 Defense tokens in hand, or passing your last action instead of Dodging. Then I try not to get too much spit on the screen. 
When judging a game, I'm excited to see every team do their best, so it makes me a little sad if I see something that definitely seems suboptimal to me.
Or not aiming a Fission Blast at range 6.
That one stings every time.
This has happened?
My goodness, I would have slapped someone.
I almost slapped my TV…
Yeah, I've never understood when people pass when they still have something left to do. Even if you don't plan on being hit, Dodge. If you've got hazards out Aim. Drives me nuts.
