Hunter Marksman Guide

Marksman is one of the more popular specs for 5v5, primarily because it has decent continuous burst damage and gives two interrupts.

Silencing Shot
Silencing shot is an amazing anti-caster ability in 5v5's because it can shut down healers at critical times and thus enable the team to burn down a primary target. Creating a focus macro and setting the focus to the opposing team's main healer can make this trivially easy: start burning down a target, then hit a focused silencing shot on the healer around the target is about to go down. In games with two healers, I can often help burn a target, then silence one healer, tab to the next and scatter and freeze him, then go back to the primary burn target.

Scatter shot
Scatter shot is yet another amazing caster interrupt as well as an escape tool for getting away from melee. Whereas in BGs I typically use scatter shot to gain distance on opponents, in arenas I will rely on blessing of freedom or other teammates to help me with this. I primarily save scatter for the same usage as silencing shot -- that is, to interrupt casters. The other main use for scatter is for interrupting rogues. As soon as a rogue starts to unload on our priest or pally, I will find him and scatter him.

Pets
Since MM pets typically don't do an extreme amount of damage, they are best used to annoy healers and casters. A pet with cobra reflexes can cause all sorts of headache on healers or cause them to waste time dealing with the pet. Note that kill command will not work if the pet is attacking a different target than the hunter; kill command only works on the target that we crit in order to enable it.

Build variants
MM builds tend to have a lot of internal variation versus difference in number of points allocated. MM specs will typically be 0/41/20 or any other variant that has at least 41 points in MM and the rest in surv. One useful talent that is often overlooked is improved stings, for viper sting. Another deceptive one is improved arcane shot, which is utterly useless in PvE but can singificant increase damage in PvP DPS which is all about spamming instants.
