How much can you play the same thing?

I'm bored. Bored with Orks.  I've done just about everything I can do with Orks and the models I have.  I have no clue on what I want to play anymore.

I do want to get going on my Tau/Necrons, but I need more models first. 

The biggest problem I see is with Orks you can't mix close combat and shooting. I've played pure shooty lists that are effective. I've played CC lists that are effective.  Trying to mix the two is where the codex really breaks down.

It's not the same thing as practicing a tournament list, which playing the same thing over and over is good. This is fun play, somewhat competitive environment and Orks. 

Mixing it up by including some CSM has helped, but it's still there to shoehorn the Helldrake in the list, with various degrees of success. 

I don't have an answer.  I'm already tired of the Iron hands, as that is strictly a competitive army, and I'm tired of the monotony of the Orks. 

So what do I do?
