This thing beat me up a bit the first time I played it. Probably because I never really thought much of pyros, man did I have a lot to learn then...
This thing opened me up to the effectiveness of pyros.

One thing though, is I might tweak the bw posistioning just a bit.
Actually, bottles bw positioning would work great for this set.
You could make a wall of knights between bw and lw (for opp games) and effectively use the same strategy as you do for same side games.

(For those of you reading saying "WTF is bottles bw position???!!!!?!?!? it is on the back wall, next to cleric, with chanty in front of cleric)

I think having both pyros on the near side is very creative and can actually be quite a threat if they sit-and-hit. Their decent health and blocking give them a chance to retreat if need be, but a scout sniping won't last long between burns.

I gave it a 9, I like everything except that both knights are on that side of the LW. I am not sure if you can do anything about it, though.

this sux when ur opponent has a chanty on the front lines
