Yeah I could see that.
After watching the way Gundy played him and a couple others, I think he's as viable for regular plebs like us as several of the other specialists in certain situations.
I guess you could argue you'd never take Gazlowe over "x" in the same way you'd never take Tychus over just about any other AA hero though. I just find Gazlowe to be in a better spot relative to his archetype than Tychus and Nova (though Nova did get a significant improvement in this patch IMO).
Can't remember it happening before unless there was a rework of the tree. I didn't know about this one either. Sounds pretty strange.
Agreed, that's where I'm going with it too. He's not great but like Nova he sort of has a lane and the bigger the hero pool gets the more viable it becomes to have heroes who are just good at a certain level of play unless you function highly with them. Tychus just plain sucks at his role right now due his AA being immobile unlike all the other AA heroes.
