Minecraft fire spreading is LAME. I wish you could burn a whole forrest down with a single spark. But you can't.

I did and experiment. I put a bunch of tall gass in a large forrest. Lit a single tree on fire, and I only got about a ten block radius of burnt.

If you are with Mojang please pitch this idea. You can take credit.

If Mojang made fire spread on dirt with grass on it (Not tall grass.) then it turned into a dirt block, like when being mined would be AWESOME. And the fire burnt longer. Not just 5 minutes.
