A generally derogatory term for Warrior Monks. Formed from the combination's acronyms: W/Mo. Often used as a synonym to describe a bad player, who doesn't understand the basics of the game.
A wammo (or "whammo") is often seen using Mending, Healing Breeze and Healing Hands as well as defensive warrior skills such as Gladiator's Defense, Dolyak Signet, and Riposte/Deadly Riposte, often with a Sword, it being a more stylish weapon in fantasy type game when compared to Axes and Hammers.
The word "wammo" comes from the phoenetical pronounciation multi-class combination of W/Mo, or Wa-Mo, while the version "whammo" carries a slightly more negative connotation as the sound "wham", which simulates the sound of a slammed door, implies the focus on brute force and lack of tactics and skill, a major concern with wammos.
The stereotypical wammo is comparable to a "paladin" in other fantasy games, and uses heavy defensive and healing skills to "tank". With this durability in mind, this stereotypical tank would charge into the fray without proper pull or aggro, making it difficult for team members, especially the healers.
In PvP, tanking is almost nonexistent as players will be able to choose targets wiseley and circumsize your defensive efforts through Enchantment removal, spike damage, or simply changing targets. Because of this, and the damage a warrior can deal, the warrior's role in PvP is that of a damage dealer. Moreover, monk and other healing/support skills are less effective on a warrior than a monk due to the lack of energy regeneration and Divine Favor.
As such, monk secondaries on warriors were frowned upon until the release of Nightfall which brought about skills such as Mending Touch which could counter or help against "You're All Alone!" and Crippling Slash Warrior, Assassin, Elementalist, and Ranger splitters who often rely on conditions. Support and utility skills on these warriors are effective because they will sometimes be forced to operate outside the reach of a monk or supporting character.
Since the release, wammos are no longer frowned upon as they have become viable options and have become short term for a Warrior Monk, and the wide usage of the term has popularized the terms "Rammo" and, to a lesser extent, "A-mmo" (usually pronounced eɪ mo) The stereotypical "whammo" using mending, however, is still a common joke among Guild Wars players.
The wammo, therefore, is viable in some situations, especially that of a split character in GvG and as a method to farm gold and items.
