The Archer can create distance between themselves and enemies, but they are not as durable as some of combat classes. Without a opponent to Elyon Gold draw the fire of enemies, Archers are vulnerable to attack from enemies. Supporting other classes with long-ranged DPS to quickly bring down targets is what an Archer does best.
Slayer
The Slayer is one of the melee classes that specialize at melee DPS. Swinging around large swords, they are front-line fighters that can mow down groups of enemies, while being strong enough to withstand attack from enemies. A Slayer's weapon is large enough to strike several opponents at once, however, they also have the ability to hit an individual enemy. Their defenses are robust enough to fulfill the function of a tank, however the Slayer performs best in situations where it knocks an adversary down as swiftly as is feasible.
A large sword will mean that a Slayer's attack speed will be slow and some skills will take a few seconds to complete. Slayers also don't have the ability to get close to long distances swiftly, which means they'll be forced to run towards attackers with range. If you are searching for a team with good offense and durability, you can't go wrong when you choose the Slayer.
Warlord
The Warlord is a melee class that can fight several enemies at the same time. Unlike the Slayer, the Warlord is an offensive melee character. The Warlord can draw the enemy's attention to themselves, giving other allies some breathing space, while hitting enemies hard.
The Warlord is able to provoke enemies and drag them to a single area. This is great for setting up attacks from the Warlord or other allies. In conjunction with the power of his skills to cheapest Elyon Gold attack several enemies simultaneously, the Warlord can keep the enemy occupied and is adept at holding their own when fighting.
