I use compression blast all the time, still prefer it over the backburner. Least the backburner is useful now though. I guess me using the compression blast makes sense, being I am a poor man.
But yeah, want to see how amazing the buff to heavy speed has made heavies? I don't really have amazing stories, just amazing numbers from mowing cowards down.
On average, I go 1-1 K:D ratio and 1.5-1 on Points to Death ratio. Now this is an extreme case to stroke my epeen with (Meowth with pocket heals ftw), but it's now around 1.7 to 2 kills on average.
I pretty much just yell at my screen with "WAAAAAAAAAAAAAAAAGH" the whole time I play heavy now.
