I'm a former HS and College debater... Here's what I would like to see:

Use your words - enunciate when giving speeches ESPECIALLY arguments that you want to highlight

The spread is ok... but remember quality over quantity, I'm looking for some depth in arguments

Know your stuff, or fake it well enough to make clear, concise points that are unrefutable

Beware of important dropped arguments - I can't debate for you. If you miss a moment to go in for the win- that opportunity is just lost.

Everyone needs to live, money needs to be saved.... and without your plan, the world ends. Or something to that effect. Basically, make me a believer using your plan and supporting evidence.
