Mass suggestion. Seems like almost everything can be "reasonable" if you're creative enough? Am I thinking of this correctly, or overlooking anything?

So I'm playing a bard and just hit level 11 and thinking of picking up mass suggestion. Spell says the succession must be reasonable but I can give a quick reason on why it's reasonable.

Example "all of you run away as far and fast as you can" isn't reasonable if they believe they can win. Nor is surrender. But "We are the vanguard force of a group numbering in the hundreds and you are moments away from annihilation, lay down your weapons and lay prone and we will capture you alive rather than kill you" sounds very reasonable.

"Give us all your money" is unreasonable "We are literally about to hold you down and cover you in alchemists fire then roast the flesh off your bones unless you give us all your money" sounds reasonable.

I've also got major illusion in my toolkit so I could definitely use that to make my suggestions a lot more compelling. "My old god horror companion is going to trap you all in a nightmare horror world that you'll never escape from if you don't surrender right now" sounds extremely reasonable

Before I pick this spell though, am I overlooking anything? Like is the average DM just gonna go "nope not reasonable they ignore you" even if my reason is compelling just so I don't completely break fights
