This is part of a series aimed at people who want to have a quick reference of viable builds for most situations.
It gives general recommendations on when to choose which build, without going deeper into gameplay strategies.

The first build includes general threat levels and short tips for heroes you might want to watch out for.

Lethal Decoys Burst Build: When the enemy team has a key target they can't do much without. (Protect the Hammer, Protect the Illidan, etc.)

Utility Build: All-purpose build for those who like to stick with their team, enabling 2v1 kills. Good when your team is lacking in the CC department.

Triple Tap Build: When your enemy made the mistake of drafting mostly squishy heroes, this will snowball you to victory. Don't forget to get a clear view before taking your 3 shots.
