Centaur Warrunner is a great hero for initiating, and nuking enemies with his abilities as well as tanking. His Hoof Stomp is an AoE stun that works for a max of 2.75 seconds and nukes, While his Double Edge is one of the spells you'll be using during most fights and is also effective against multiple enemies so use it to farm as well, Return is an ability that makes him counter attacks, while finally his Stampede makes you and all allies run at max speed and trample enemies to slow them.
