ETC is a great Warrior for heroes who need setup to land their combos. Since Kel’thuzad’s abilities can be hard to land in a vacuum, heroes who are strong at grouping or isolating enemies are great when paired with him. Mosh Pit also synergizes particularly well with Kel’thuzad, as he can put out an incredible amount of damage when the enemy is unable to move.

Alarak and Kel’thuzad are both heroes who are great at capitalizing on the mistakes of their enemies. If an enemy hero steps slightly out of position, they can find themselves quickly pulled into the opposing team via Alarak’s Telekinesis, or pulled to their teammates with Kel’thuzad’s Chains. Either way, once one of these paired heroes lands an ability on an enemy, the other one can quickly follow up, resulting in devastating damage or even a quick kill.

Kel’thuzad struggles against high-mobility, diving heroes who can easily dodge his skill shots. Landing a Chain is hard enough on its own against someone like Tracer, and even when one Chain lands, it’s that much harder to land the second one with her zipping around.

Li-Ming’s high mobility and heavy burst combined can be a nightmare for Kel’thuzad to deal with. She out-pokes him as well and is a large enough threat that if he stands still for any length of time to try to land his abilities, he risks taking heavy damage.

Kel’thuzad is all about heavy CC combined with high burst damage. Uther’s able to mitigate burst damage by adding Armor to his allies, and has strong anti-CC talents that he has access to fairly early in the game, which combined can completely ruin what would otherwise be a great setup for Kel’thuzad.
