While your quote is old, it still fits. I've had Gazlowe on my team several times who sits there and just tries to melee heroes or something stupid. Everytime I see one on my team I want to /facepalm.
Now on the other hand Gazlowe is my favorite hero and I tend to play him when I'm not getting the others to level 4 for their skills. I've had I don't know how many messages at the end of the game on how well I did. I think it's mainly because I love Gaz and how he run around and merc like crazy. Usually when I do it the mercs make a big difference and help either push through bottom/top defenses easily or it'll distract 2-3 of their team members so the rest of my team can push elsewhere/kill hereos.
