I remember when Heavy sucked. No GRU, no sandvich, minigun could hit anything for shit and take long to spin up and spin down.
Now Heavy is powerful enough people joke saying if your team wants to win, just start choosing heavy + medic combos and faceroll for victory.
It's interesting to see the face of the game change from the way it was played at launch to the way it is played now but I ponder which way was better. Being a Heavy player I am biased of course, I don't miss the past.
I think the game focus switched from Demoman to Heavy and unless the map force otherwise.
I expect a rise in the popularity of Scout with the new QuickFix gun. Medics, beware.
