Public Speaking Speech Ideas

[Xx{Midnight}xX]

So I'm in a public speaking course, as the title pretty much says, and I am coming up on having to give a persuasive speech. I am however having issues settling for a good topic in stone.

The only major requirement to keep in mind for this whole discussion is that I have to keep it as close to seven minutes as possible, and I have to be able to argue it.

But pretty much I am having issues coming up with a topic that I think can be done "well."

I had to use an "umbrella topic" which I have chosen already to be E-sports (online gaming.)

Here's a few I have come up with:

1. Dissecting a simchart and explaining why I think things should have/how it could have been done differently.
2. Explaining why the legacy charts should be removed from the game.
3. Arguing Semipent VS Spread VS Hybrid Spread their advantages and why certain uses of each style is better than the other.
4. Why they should try FFR out as a way to relax.

But I feel adapting these to the audience, who I know is borderline clueless to FFR, save for the fourth one, will be somewhat difficult without a really generalized argument. Does anyone here have an idea of how to modify one of the four topics above, or a better topic overall?
