For beginners, a 'Grinder' or 'Armorer' build is often recommended. A Grinder build (using the Grinder perk deck) focuses on health regeneration through damage, making you very survivable. An Armorer build (using the Armorer perk deck) emphasizes heavy armor and damage reduction, allowing you to tank more hits. Both are forgiving and effective for learning the game's mechanics in loud heists.
