Prevent Server Jumping with rewards!

Howdy

Its a real pain to get into a good server with a good team in a public run, so when it does happen it would be great if there was some mechanism to retain the people on the server to play again. At moment there is no incentive to stay on the server, some people leave once the Boss is dead and don't even kill all the remaining bots.

So the idea is to add an XP boost if you stay on the server. If you get to wave 21(e.g you kill all the bots and boss and the server resets on new map) you should get a xp boost for the next game if and only if you stay on the server. And then make that stack, 

Normal (Bigger numbers here to help the noobs level faster)
Game 1 10% XP Boost
Game 2 15% XP Boost
Game 3 20% XP Boost
Stay at 20% for every game after until server jump.

Hard 
Game 1 5% XP Boost
Game 2 10% XP Boost
Game 3 15% XP Boost
Stay at 15% for every game after until server jump.

Hard 
Game 1 2% XP Boost
Game 2 4% XP Boost
Game 3 8% XP Boost
Stay at 8% for every game after until server jump.

If a run falls apart you lose the bonus.
Should not be allowed on Event servers I imagine. 

Just a an idea. I really hate when a hard run breaks up and then there is no more hard runs for a while as most people jump into normal games. 
Just a suggestion.
