I disagree with most of these guides. Don't forget each player has their own personal tactics and style of play, and builds of GVH keep coming out which can completely kill one strategy and create another. So don't argue about it, cause there'll never be a definitive GVH guide 
My cousin (Some of you may know him as Odin) always using Hunter + Lightning, and he never misses, so he's a real threat.
If he can't get best aim of that, he'll take a pick at Ice arrows and get as close as possible by eliminating the threat, whether he took the fraggin' himself or not, but he's DEFINITELY a tactician. He tells me "If your dead, boo-hoo, but if you can stop the enemy, then gj, mate!"
But what cutman said : Everybody has their own way of handling something.
